0:00:00.000,0:00:01.679
so how bad do you think[br]this carabiner is?
0:00:01.679,0:00:04.400
it's really bad... it's super super sharp
0:00:04.400,0:00:07.879
super super sharp?[br]it's not only a little bit worn out
0:00:07.879,0:00:08.880
it's super sharp
0:00:08.880,0:00:11.119
where did you got it from from? [br]from a crag
0:00:11.119,0:00:15.199
so this is a real carabiner[br]from real crag
0:00:15.199,0:00:17.480
yes, there was an accident[br]in this crag
0:00:17.480,0:00:19.519
and the climber...
0:00:19.519,0:00:21.640
died...
0:00:21.640,0:00:24.079
as you can see it's really sharp
0:00:24.079,0:00:27.280
I want to feel it
0:00:27.679,0:00:31.120
it doesn't feel that sharp for me
0:00:31.120,0:00:32.200
i mean it's not a knife
0:00:32.200,0:00:33.280
yeah yeah yeah
0:00:33.280,0:00:35.679
but like for a rope this is enough
0:00:35.679,0:00:37.000
good to know...
0:00:37.640,0:00:39.079
right
0:00:39.079,0:00:40.840
i don't know about you
0:00:40.840,0:00:43.479
but personally i never had to witness
0:00:43.479,0:00:46.359
anybody completely snapping his or her
0:00:46.359,0:00:47.719
climbing rope
0:00:47.719,0:00:50.359
during a real climbing fall but
0:00:50.359,0:00:52.920
unfortunately it happens
0:00:52.920,0:00:54.119
so
0:00:54.119,0:00:56.200
people who watch my channel
0:00:56.200,0:00:58.200
and have fear of falling
0:00:58.200,0:01:01.399
watch this video and they will have more
0:01:01.399,0:01:03.479
fear of falling after it
0:01:03.479,0:01:05.319
now if you're one of these more
0:01:05.319,0:01:08.280
sensitive people don't worry just
0:01:08.280,0:01:11.079
imagine me holding your hand as i guide
0:01:11.079,0:01:13.480
you through this video and everything is
0:01:13.480,0:01:16.599
gonna be fine. Okay jokes aside this is a
0:01:16.599,0:01:19.560
part two of my conversations with rope
0:01:19.560,0:01:22.200
experts from Mammut, where in a part one
0:01:22.200,0:01:24.840
i showed you how a soft spot in your
0:01:24.840,0:01:27.719
climbing rope can easily end up in a
0:01:27.719,0:01:30.760
broken sheath on a realistic climbing
0:01:30.760,0:01:34.120
fall we broke the sheath after two falls
0:01:34.120,0:01:36.519
and you said it's gonna last
0:01:36.519,0:01:38.439
something like this
0:01:38.439,0:01:41.159
unfortunately i've seen this way too
0:01:41.159,0:01:43.879
many times the good news as we saw in
0:01:43.879,0:01:46.200
that video that even with completely
0:01:46.200,0:01:49.000
broken sheath the rope was still hard to
0:01:49.000,0:01:49.959
snap
0:01:49.959,0:01:52.840
*the bad news is that the core strands
0:01:52.840,0:01:56.519
are way easier to cut
0:01:58.040,0:02:00.200
somebody said of course it's easy to cut
0:02:00.200,0:02:02.760
when you use a swiss army knife so this
0:02:02.760,0:02:05.799
is not a swiss army knife it's actually
0:02:05.799,0:02:08.199
quite dull this is 80 kilograms and this
0:02:08.199,0:02:10.680
is a rope
0:02:17.240,0:02:21.800
okay that was not that hard
0:02:21.800,0:02:25.159
let's get rid of the sheath
0:02:29.319,0:02:31.960
okay so now the climber is hanging only
0:02:31.960,0:02:35.719
on core strands let's see how
0:02:35.719,0:02:37.479
hard it is to cut
0:02:37.479,0:02:40.439
the core strands
0:02:47.479,0:02:49.639
so if during the fall you would lose
0:02:49.639,0:02:52.039
your sheath and then your rope would run
0:02:52.039,0:02:54.759
across a sharp edge
0:02:54.759,0:02:56.680
so assuming that you take care of your
0:02:56.680,0:02:59.080
rope and it's in a good condition
0:02:59.080,0:03:01.719
then you still have to quite often
0:03:01.719,0:03:05.080
overlook dangers
0:03:06.120,0:03:08.039
so first
0:03:08.039,0:03:10.680
is all the equipment that your rope goes
0:03:10.680,0:03:12.560
through
0:03:12.560,0:03:25.800
[Music]
0:03:27.159,0:03:29.400
oh
0:03:29.479,0:03:32.439
so this was a new quickdraw before i
0:03:32.439,0:03:35.400
did that and as you can see the paint at
0:03:35.400,0:03:38.280
this point is already wearing off and if
0:03:38.280,0:03:40.360
i would continue doing that or i would
0:03:40.360,0:03:42.360
just go climbing and take falls on this
0:03:42.360,0:03:44.520
quickdraw this part would develop a
0:03:44.520,0:03:46.919
groove something like this
0:03:46.919,0:03:50.199
or in some cases even worse so a little
0:03:50.199,0:03:52.439
groove after some time of climbing is
0:03:52.439,0:03:55.159
definitely normal and usually it's not a
0:03:55.159,0:03:57.639
problem since the rope makes it nice
0:03:57.639,0:04:00.199
smooth and round
0:04:00.199,0:04:03.159
usually but not always
0:04:03.159,0:04:05.879
like in the story where the climber died
0:04:05.879,0:04:08.120
the situation was like this the route
0:04:08.120,0:04:10.599
was traversing under the roof and the
0:04:10.599,0:04:13.000
crux was after a second quick draw
0:04:13.000,0:04:15.319
that's where everybody kept falling and
0:04:15.319,0:04:17.800
this quickdraw probably had a nice and
0:04:17.800,0:04:19.399
round edge
0:04:19.399,0:04:22.120
however this quickdraw only seen a
0:04:22.120,0:04:24.839
sideways motion sideways friction from
0:04:24.839,0:04:28.360
the rope and nobody ever fell on it
0:04:28.360,0:04:32.120
until one day a climber took a fall
0:04:32.120,0:04:35.079
and his rope was cut on this quickdraw
0:04:35.079,0:04:37.959
do you test how your ropes are resistant
0:04:37.959,0:04:40.439
to cutting and are there any standards
0:04:40.439,0:04:42.680
start with the second question first so
0:04:42.680,0:04:45.560
and no there are no standard tests for
0:04:45.560,0:04:47.319
the cut resistance i mean in the
0:04:47.319,0:04:50.120
standard today this default test which i
0:04:50.120,0:04:52.279
think everyone has seen a million times
0:04:52.279,0:04:54.839
but here the rope falls over a clamp
0:04:54.839,0:04:57.480
that's very similar to a new carabiner
0:04:57.480,0:05:00.040
so to demonstrate how bad a sharp
0:05:00.040,0:05:01.560
carabiner can be
0:05:01.560,0:05:03.959
we took a brand new rope and rigged a
0:05:03.959,0:05:06.439
realistic fall scenario
0:05:06.439,0:05:08.920
this is 9.5
0:05:08.920,0:05:11.639
grand euro
0:05:12.759,0:05:13.720
oh
0:05:13.720,0:05:15.720
first of all brand new rope
0:05:15.720,0:05:19.240
entire sheath of the rope got wrecked the
0:05:19.240,0:05:21.160
force in area is really it's nothing
0:05:21.160,0:05:23.720
hard i'm actually shocked by this like
0:05:23.720,0:05:27.360
this is crazy. Now we change to the one
0:05:27.360,0:05:28.360
the old rope
0:05:28.360,0:05:30.600
let's see what happens if your rope is
0:05:30.600,0:05:33.000
actually fuzzy and old so we take the
0:05:33.000,0:05:35.399
same old rope we find another spot which
0:05:35.399,0:05:38.199
is quite fuzzy it's
0:05:38.199,0:05:40.439
definitely people would still climb on
0:05:40.439,0:05:41.319
this
0:05:41.319,0:05:42.759
soft
0:05:42.759,0:05:45.399
but not completely bad
0:05:45.399,0:05:47.720
will it snap no you think it will not
0:05:47.720,0:05:48.680
snap
0:05:48.680,0:05:51.079
how many lives the quarter will lose
0:05:51.079,0:05:54.199
two strands will be snapped of the core
0:05:54.199,0:05:56.360
okay, and the sheath. Okay his guess is
0:05:56.360,0:05:58.600
two out of eight
0:06:02.199,0:06:04.439
so half of the core's strands snapped, so
0:06:04.439,0:06:05.519
on the old rope half
0:06:05.519,0:06:06.499
of the strands snapped
0:06:06.519,0:06:07.439
on the new one none
0:06:07.439,0:06:08.680
[Music]
0:06:08.680,0:06:10.759
it's still good to know that even the
0:06:10.759,0:06:13.720
old old rope kind of survived but if the
0:06:13.720,0:06:16.120
fall would be bigger a little bit bigger
0:06:16.120,0:06:18.439
i mean then it would snap be careful
0:06:18.439,0:06:19.959
with sharp edges
0:06:19.959,0:06:22.680
a couple of years ago UIAA tried to
0:06:22.680,0:06:25.639
implement a cut resistant test where the
0:06:25.639,0:06:27.879
rope had a dynamic fall over a sharp
0:06:27.879,0:06:29.800
edge i think it was a year or two on the
0:06:29.800,0:06:32.279
market and then it they cancel it
0:06:32.279,0:06:33.319
because the
0:06:33.319,0:06:35.480
testing it did not work
0:06:35.480,0:06:38.600
now yeah hillary they have their own
0:06:38.600,0:06:41.800
test method and we are also looking into
0:06:41.800,0:06:44.519
this actually since a long long time the
0:06:44.519,0:06:47.639
rope takes a dynamic fall over a granite
0:06:47.639,0:06:51.079
edge and slides over this granite edge
0:06:51.079,0:06:53.319
so at the moment it's up to the brands
0:06:53.319,0:06:55.399
themselves to do their internal testing
0:06:55.399,0:06:56.519
there is no
0:06:56.519,0:07:00.120
universal standard correct it will come
0:07:00.120,0:07:02.519
one day so now the climber is hanging
0:07:02.519,0:07:04.839
only on four strands of the rope and we
0:07:04.839,0:07:07.639
are gonna show how much it takes to
0:07:07.639,0:07:09.399
completely snap the rope if you just
0:07:09.399,0:07:13.759
barely touch with the knife
0:07:14.360,0:07:16.040
it's crazy
0:07:16.040,0:07:18.439
it's just nothing yeah he barely touched
0:07:18.439,0:07:21.240
with the sharp edge and it snapped yeah
0:07:21.240,0:07:22.680
this is the
0:07:22.680,0:07:25.959
the carabiner we did the test with now
0:07:25.959,0:07:28.680
it doesn't feel like a knife but the
0:07:28.680,0:07:30.839
groove is very deep it's definitely at
0:07:30.839,0:07:33.160
the edges it's sharp
0:07:33.160,0:07:34.519
but it's
0:07:34.519,0:07:37.480
not something that i would expect out of
0:07:37.480,0:07:40.199
snapping the rope like that so please
0:07:40.199,0:07:42.199
take care of your carabiners and if
0:07:42.199,0:07:45.000
you're climbing on fixed carabiners
0:07:45.000,0:07:46.920
make sure to check them as well
0:07:46.920,0:07:50.279
it's a deep groove but somehow i was
0:07:50.279,0:07:54.040
expecting an a sharper edge to be honest
0:07:54.040,0:07:58.680
because it still feels kind of smooth
0:07:59.879,0:08:00.920
good to know
0:08:00.920,0:08:02.680
good to know definitely
0:08:02.680,0:08:04.839
so in addition to ropes chewing through
0:08:04.839,0:08:07.079
your quick draws you should also be
0:08:07.079,0:08:09.720
aware how and where you clip your quick
0:08:09.720,0:08:12.279
draws for example this one the rope
0:08:12.279,0:08:14.199
should be only clipped to the blue
0:08:14.199,0:08:16.439
carabiner and if you don't know why you
0:08:16.439,0:08:18.680
should watch my master class on quick
0:08:18.680,0:08:21.000
draws let's say for whatever reason i
0:08:21.000,0:08:23.480
want to connect myself to the bolt using
0:08:23.480,0:08:27.079
a quickdraw if i would do this
0:08:27.079,0:08:29.319
this is actually a really bad idea
0:08:29.319,0:08:32.440
because the bolt can leave a sharp cut
0:08:32.440,0:08:35.080
on this carabiner and this carabiner
0:08:35.080,0:08:37.639
later will get in contact with the rope
0:08:37.639,0:08:39.240
so instead of that
0:08:39.240,0:08:41.480
do the opposite
0:08:41.480,0:08:43.399
the carabiner which is designed to go to
0:08:43.399,0:08:45.639
the bolt goes to the bolt and the rope
0:08:45.639,0:08:47.559
and goes to something soft there was
0:08:47.559,0:08:49.080
also for example an accident in
0:08:49.080,0:08:51.559
switzerland in mountain guide aspirant
0:08:51.559,0:08:53.879
courses one mountain guide lowered two
0:08:53.879,0:08:56.759
person on one strand 8.7 millimeter
0:08:56.759,0:08:58.759
diameter he lowered them
0:08:58.759,0:09:01.000
both on this single strand and then like
0:09:01.000,0:09:03.000
one and a half meters below his feet
0:09:03.000,0:09:05.000
there was like an edge but really like
0:09:05.000,0:09:07.080
we we had a look at it it was not a
0:09:07.080,0:09:09.480
sharp edge i would say it's it's just
0:09:09.480,0:09:12.440
like a normal edge which you find like
0:09:12.440,0:09:15.159
in every direction, you are scaring my
0:09:15.159,0:09:18.759
viewers the whole rope um got got cut and
0:09:18.759,0:09:20.840
this brings us to a second danger for
0:09:20.840,0:09:22.440
climbing ropes
0:09:22.440,0:09:25.320
sharp rock formations so if you're a
0:09:25.320,0:09:27.960
sensitive person now it's a time to hold
0:09:27.960,0:09:31.120
my hand
0:09:41.159,0:09:43.799
so the climber actually survived
0:09:43.799,0:09:46.840
and this is an old video posted by
0:09:46.840,0:09:49.399
british mountaineering council
0:09:49.399,0:09:54.519
and i guess the clip speaks for itself
0:09:56.919,0:10:00.039
do you have any statistics on accidents
0:10:00.039,0:10:02.679
that happen due to snapping climbing
0:10:02.679,0:10:05.480
rope so the best statistic that i know
0:10:05.480,0:10:07.320
of is the one from the german alpine
0:10:07.320,0:10:10.759
club they actually kept the register
0:10:10.759,0:10:12.840
of all the rope accidents that took
0:10:12.840,0:10:16.440
place i think was for the last 60 years
0:10:16.440,0:10:17.639
there they have
0:10:17.639,0:10:20.279
53 cases where they know
0:10:20.279,0:10:21.080
why
0:10:21.080,0:10:24.120
the rope broke and what's the most common
0:10:24.120,0:10:27.399
cause sharp edges sharp edges
0:10:27.399,0:10:29.000
66 percent
0:10:29.000,0:10:31.320
so when the fall happens and you swing
0:10:31.320,0:10:34.039
over the sharp edge either you take a
0:10:34.039,0:10:37.559
fall over a sharp edge or you're lowered
0:10:37.559,0:10:40.440
over a sharp edge or you're
0:10:40.440,0:10:42.279
you know you're taking some kind of
0:10:42.279,0:10:45.000
swing over a sharp edge but it's not
0:10:45.000,0:10:47.240
only the rock formation it can also be
0:10:47.240,0:10:50.600
due to carabiners sharp carabiners or
0:10:50.600,0:10:51.399
other
0:10:51.399,0:10:54.120
metal objects and speaking of statistics
0:10:54.120,0:10:56.279
i asked my instagram followers to send
0:10:56.279,0:10:59.720
me stories pictures videos about rope
0:10:59.720,0:11:03.399
damage and while i got no complete snaps
0:11:03.399,0:11:04.320
i got this one
0:11:04.320,0:11:06.559
which looks like it got a lot of
0:11:06.559,0:11:09.440
abrasion and this one was hit by a rock
0:11:09.440,0:11:12.000
with just few strands left and this is
0:11:12.000,0:11:14.399
my favorite one it was actually a brand
0:11:14.399,0:11:17.120
new rope only three falls and the owner
0:11:17.120,0:11:19.679
claims that there was no sharp edges and
0:11:19.679,0:11:22.320
the quick draws were fine the only catch
0:11:22.320,0:11:25.600
with this rope was 8.9 millimeters
0:11:25.600,0:11:27.919
thickness only do you see a difference
0:11:27.919,0:11:30.639
in cut resistance among thicker ropes
0:11:30.639,0:11:33.519
versus thinner ropes oh yes so i mean if
0:11:33.519,0:11:36.240
you want a higher safety margin i mean
0:11:36.240,0:11:39.200
the thicker the rope is the better so
0:11:39.200,0:11:42.480
how much safer is let's say 9.8 rope
0:11:42.480,0:11:45.759
compared to 9.5 or 9.2 so turns out
0:11:45.759,0:11:47.679
Mammut already did the testing on this
0:11:47.679,0:11:50.159
where we use the same sharp carabiner
0:11:50.159,0:11:53.039
and checked at what fall height the rope
0:11:53.039,0:11:55.279
will snap and these were the results so
0:11:55.279,0:11:57.600
we had all heights up to five meters and
0:11:57.600,0:12:01.200
we tested like different rope diameters
0:12:01.200,0:12:02.080
and
0:12:02.080,0:12:03.919
like a half and twin rope and to no
0:12:03.919,0:12:06.720
surprise thicker ropes perform better
0:12:06.720,0:12:09.440
with double robes being the safest and
0:12:09.440,0:12:11.759
this actually brings me to a current
0:12:11.759,0:12:14.480
trend where people buy ultra skinny
0:12:14.480,0:12:16.960
ropes thinking that they are the best
0:12:16.960,0:12:19.679
maybe if you're not at that level where
0:12:19.679,0:12:22.240
it's like so so important for you every
0:12:22.240,0:12:26.000
gram every little millimeter of the rope
0:12:26.000,0:12:27.440
maybe it's not
0:12:27.440,0:12:29.600
important to buy the thinnest rope you
0:12:29.600,0:12:32.000
can on the market i mean if you can
0:12:32.000,0:12:33.840
i would recommend having two ropes now
0:12:33.840,0:12:36.000
you have the the thicker one for for
0:12:36.000,0:12:38.320
working out the routes and one you can
0:12:38.320,0:12:39.440
also
0:12:39.440,0:12:41.840
use when you know how you feel like oh
0:12:41.840,0:12:44.240
this route could be a little bit
0:12:44.240,0:12:46.639
sketchy there with some sharp edges then
0:12:46.639,0:12:48.080
you take the thick rope and then you
0:12:48.080,0:12:50.559
have a thinner rope which you might use
0:12:50.559,0:12:51.440
when you
0:12:51.440,0:12:53.120
already checked out the route and you
0:12:53.120,0:12:55.200
want to have a really good goal in
0:12:55.200,0:12:57.360
sanding the roots so this video is not
0:12:57.360,0:12:59.679
sponsored but a little disclaimer is
0:12:59.679,0:13:01.759
that i got these ropes for free from
0:13:01.759,0:13:04.159
Mammut and i have to say that climbing
0:13:04.159,0:13:07.399
my hardest projects on this ultra skinny
0:13:07.399,0:13:11.120
9.0 rope was really nice
0:13:20.159,0:13:23.120
however for anything new unknown my
0:13:23.120,0:13:25.679
go-to rope is nine and a half
0:13:25.679,0:13:27.360
millimeters thickness
0:13:27.360,0:13:29.279
and if i would have to choose just one
0:13:29.279,0:13:32.080
rope to own this would be it and i guess
0:13:32.080,0:13:34.399
if i would be climbing in some sketchier
0:13:34.399,0:13:36.639
places or i would be
0:13:36.639,0:13:38.559
heavier i hope not maybe i would
0:13:38.559,0:13:41.440
consider even thicker rope than that
0:13:41.440,0:13:43.600
it's pretty obvious that falls like this
0:13:43.600,0:13:46.320
should be avoided at all cost but in
0:13:46.320,0:13:49.360
general if the rope is running across a
0:13:49.360,0:13:50.799
sharp edge
0:13:50.799,0:13:54.240
soft dynamic delaying is actually very
0:13:54.240,0:13:56.480
important because if the belayer takes
0:13:56.480,0:13:59.039
really hard that increases the peak
0:13:59.039,0:14:01.600
force on the rope and also the damage
0:14:01.600,0:14:04.559
will be concentrated on a smaller area
0:14:04.559,0:14:07.120
of the rope so more things to go wrong
0:14:07.120,0:14:09.519
okay let's change gears you guys asked
0:14:09.519,0:14:12.720
me what about unicore rose sounds almost
0:14:12.720,0:14:15.840
like unicorn so a unicore rope has its
0:14:15.840,0:14:18.639
core and sheath strands kind of hooked
0:14:18.639,0:14:21.679
together so this is not a unicore rope
0:14:21.679,0:14:25.200
and if i would pull the sheath
0:14:25.200,0:14:27.279
you can see that they are completely
0:14:27.279,0:14:30.559
independent and this would not happen on
0:14:30.559,0:14:33.039
unicore ropes if a rope is developed
0:14:33.039,0:14:35.360
well the sheath and the core are
0:14:35.360,0:14:38.320
perfectly matched together so they can
0:14:38.320,0:14:41.279
move very well why don't you hook them
0:14:41.279,0:14:43.759
together i saw some brands doing that is
0:14:43.759,0:14:46.399
there any benefit of doing one or other
0:14:46.399,0:14:49.919
way you can do this but nowadays the
0:14:49.919,0:14:52.879
ropes are so well designed that
0:14:52.879,0:14:55.600
for example sheath slippage does not
0:14:55.600,0:14:58.799
occur that often anymore actually
0:14:58.799,0:15:01.600
on most of the ropes not most on all of
0:15:01.600,0:15:03.840
our ropes we have a sheath slippage of
0:15:03.840,0:15:06.320
zero and this is without intertwining
0:15:06.320,0:15:07.919
the sheath with the core what does it
0:15:07.919,0:15:11.840
mean zero shift slippage if you
0:15:11.840,0:15:14.080
pull the rope over an edge back and
0:15:14.080,0:15:16.879
forth how much the core
0:15:16.879,0:15:19.200
would move to one side or the other but
0:15:19.200,0:15:20.960
if it stays in place then it's well
0:15:20.960,0:15:24.000
balanced yeah i've seen some ropes lose
0:15:24.000,0:15:26.720
the core in the ends of the rope yes the
0:15:26.720,0:15:29.519
ends get completely soft yeah so this is
0:15:29.519,0:15:31.919
actually what sheath slippage is is that
0:15:31.919,0:15:33.919
the core and the sheath
0:15:33.919,0:15:37.120
don't move at the same pace basically
0:15:37.120,0:15:40.000
so your ropes don't do that
0:15:40.000,0:15:43.360
so as i understand intertwining the core
0:15:43.360,0:15:46.480
with sheath doesn't add much benefit for
0:15:46.480,0:15:48.080
sport climbers
0:15:48.080,0:15:50.480
however if you are ascending a rope
0:15:50.480,0:15:52.480
let's say you marrying a rope and your
0:15:52.480,0:15:54.399
sheath gets cut
0:15:54.399,0:15:55.600
it can
0:15:55.600,0:15:57.919
slide down
0:15:57.919,0:16:01.159
kind of
0:16:01.519,0:16:03.440
well it can slide down
0:16:03.440,0:16:04.480
here
0:16:04.480,0:16:06.080
this can happen
0:16:06.080,0:16:08.399
but this sliding would not happen on a
0:16:08.399,0:16:10.559
unicore rope so yeah i don't know if i'm
0:16:10.559,0:16:12.720
missing some benefits of unicore ropes
0:16:12.720,0:16:15.360
for sport climbers let me know i'm super
0:16:15.360,0:16:18.080
curious all right i hope that your fear
0:16:18.080,0:16:20.240
of falling is under control and maybe
0:16:20.240,0:16:22.240
you even learned something
0:16:22.240,0:16:25.120
and i'm gonna release more interviews
0:16:25.120,0:16:27.519
with Mammut engineers about some more
0:16:27.519,0:16:30.320
geeky topics about climbing ropes and
0:16:30.320,0:16:32.480
that's going to be exclusive for people
0:16:32.480,0:16:35.200
who are supporting my channel so if you
0:16:35.200,0:16:38.240
are interested in that or you just want
0:16:38.240,0:16:40.480
to support me consider visiting my
0:16:40.480,0:16:43.039
website and thank you so much and thank
0:16:43.039,0:16:45.200
you Mammut for inviting me and i hope
0:16:45.200,0:16:47.440
to come back one day why is that why
0:16:47.440,0:16:50.720
some ropes get stiffer and softer well
0:16:50.720,0:16:54.000
to answer that question like textiles is
0:16:54.000,0:16:57.440
a very tricky and moody raw material to
0:16:57.440,0:16:59.879
work with moody it's very moody
