2
00:00:01,280 --> 00:00:03,840
so here is a cool fact

3
00:00:03,840 --> 00:00:06,560
rope manufacturers claim that no matter

4
00:00:06,560 --> 00:00:09,280
what fall you will take on a dynamic

5
00:00:09,280 --> 00:00:10,719
climbing rope

6
00:00:10,719 --> 00:00:12,320
the impact

7
00:00:12,320 --> 00:00:17,080
is unlikely to injure you

8
00:00:18,320 --> 00:00:20,000
that was sick

9
00:00:20,000 --> 00:00:21,680
so how does it feel this

10
00:00:21,680 --> 00:00:26,320
impact on a huge outside whipper

11
00:00:26,320 --> 00:00:29,439
or this is even better how does it feel

12
00:00:29,439 --> 00:00:32,239
to fall while trying to clip a second

13
00:00:32,239 --> 00:00:37,680
quick draw and get a really hard catch

14
00:00:39,440 --> 00:00:42,480
so can this impact injure you does it

15
00:00:42,480 --> 00:00:44,559
hurt

16
00:00:44,559 --> 00:00:45,440
or

17
00:00:45,440 --> 00:00:46,879
even better

18
00:00:46,879 --> 00:00:48,719
how does it feel when i'm trying to

19
00:00:48,719 --> 00:00:50,800
explain all of this

20
00:00:50,800 --> 00:00:54,320
and almost kill myself

21
00:00:55,840 --> 00:00:59,680
so yeah that happened and it all started

22
00:00:59,680 --> 00:01:02,879
with my wish to measure the forces of

23
00:01:02,879 --> 00:01:06,080
really really hard climbing falls

24
00:01:06,080 --> 00:01:08,799
and knowing these forces allow me and

25
00:01:08,799 --> 00:01:11,040
probably others to answer a lot of

26
00:01:11,040 --> 00:01:13,760
important questions for us climbers

27
00:01:13,760 --> 00:01:16,799
like can you break a dynamic climbing

28
00:01:16,799 --> 00:01:21,759
rope which is really really worn out

29
00:01:23,600 --> 00:01:26,399
on realistic climbing falls

30
00:01:26,399 --> 00:01:27,300
some people

31
00:01:27,300 --> 00:01:29,920
would say that it is impossible to break

32
00:01:29,920 --> 00:01:32,400
this rope while others would freak out

33
00:01:32,400 --> 00:01:33,680
seeing this

34
00:01:33,680 --> 00:01:35,920
because it doesn't look that great to be

35
00:01:35,920 --> 00:01:37,119
honest

36
00:01:37,119 --> 00:01:40,000
so stick with me the answer to this is

37
00:01:40,000 --> 00:01:41,040
coming

38
00:01:41,040 --> 00:01:45,280
and it actually surprised me a lot

39
00:01:45,280 --> 00:01:49,680
but now back to hard falls

40
00:01:53,119 --> 00:01:55,360
so in previous episode we went to a

41
00:01:55,360 --> 00:01:58,000
small climbing gym in germany and we

42
00:01:58,000 --> 00:02:00,799
tried to create the hardest climbing fall

43
00:02:00,799 --> 00:02:03,680
by creating a ton of drag

44
00:02:03,680 --> 00:02:09,079
and belaying in some crazy crazy ways

45
00:02:11,200 --> 00:02:13,440
and then i had a quiz for you

46
00:02:13,440 --> 00:02:16,890
which fall do you think was harder for
the climber

47
00:02:16,890 --> 00:02:19,520
this crazy slam

48
00:02:19,520 --> 00:02:24,319
or this big outdoors whipper

49
00:02:29,920 --> 00:02:33,280
so if you think that the big fall

50
00:02:33,280 --> 00:02:35,200
looks softer

51
00:02:35,200 --> 00:02:38,000
good because i thought exactly the same

52
00:02:38,000 --> 00:02:40,720
thing and pretty much any person to whom

53
00:02:40,720 --> 00:02:42,485
i showed these two clips

54
00:02:42,485 --> 00:02:44,119
i'm gonna show you two falls

55
00:02:44,140 --> 00:02:46,080
and you can try to guess which one was

56
00:02:46,080 --> 00:02:48,400
harder to the climber 
- okay

57
00:02:48,400 --> 00:02:51,040
yeah i can already tell you

58
00:02:51,040 --> 00:02:53,200
well theoretically i would say that the

59
00:02:53,200 --> 00:02:55,791
second one in the gym is the harder fall

60
00:02:55,791 --> 00:02:58,640
because it's a shorter rope that can

61
00:02:58,640 --> 00:03:01,360
absorb or a shorter portion of the rope

62
00:03:01,360 --> 00:03:03,360
will absorb the energy

63
00:03:03,360 --> 00:03:05,599
since there's so much zigzag happening

64
00:03:05,599 --> 00:03:08,239
in the rope line and therefore yeah not

65
00:03:08,239 --> 00:03:10,481
the entire rope that is actually used

66
00:03:10,481 --> 00:03:15,160
so let's see if that's actually true

67
00:03:15,160 --> 00:03:18,159
[Music]

68
00:03:18,159 --> 00:03:19,520
that was sick

69
00:03:19,520 --> 00:03:25,519
[Music]

70
00:03:25,519 --> 00:03:27,760
that was sick

71
00:03:27,760 --> 00:03:30,879
that was like a massive fall

72
00:03:30,879 --> 00:03:31,994
it was

73
00:03:31,994 --> 00:03:33,330
falling was nice

74
00:03:33,330 --> 00:03:36,560
how big you think the fall was

75
00:03:36,879 --> 00:03:39,760
how hard to say i will say like

76
00:03:39,760 --> 00:03:42,080
eight meters maybe

77
00:03:42,080 --> 00:03:44,480
it looked massive from the side it

78
00:03:44,480 --> 00:03:45,999
looked massive

79
00:03:45,999 --> 00:03:47,519
maybe 10

80
00:03:47,519 --> 00:03:49,680
i don't know

81
00:03:49,680 --> 00:03:52,000
do you think it's more than 10

82
00:03:52,000 --> 00:03:53,680
yeah from the side it looks massive

83
00:03:53,680 --> 00:03:56,400
I think more it was more to 15 i would say

84
00:03:56,400 --> 00:03:57,200
you know

85
00:03:57,200 --> 00:03:59,680
you don't think so 15

86
00:03:59,680 --> 00:04:01,599
no i don't think so i don't think so

87
00:04:01,599 --> 00:04:03,760
yeah judging the distance of

88
00:04:03,760 --> 00:04:06,959
the fall is always tricky but by my best

89
00:04:06,959 --> 00:04:09,599
estimation before the fall he was around

90
00:04:09,599 --> 00:04:12,239
two and a half meters above the bolt and

91
00:04:12,239 --> 00:04:14,959
after the fall he was about eight meters

92
00:04:14,959 --> 00:04:18,160
below the bolt so let's say 10 meters

93
00:04:18,160 --> 00:04:23,280
and this 10 meters fall resulted into

94
00:04:24,199 --> 00:04:28,479
3.4 kilonewtons of force and if we

95
00:04:28,479 --> 00:04:31,360
compare that to the jim slam

96
00:04:31,360 --> 00:04:35,360
that slam was only 2.6 kilonewtons and

97
00:04:35,360 --> 00:04:37,680
the hardest fall in the gym that day we

98
00:04:37,680 --> 00:04:42,960
got was 2.9 kilonewtons this one

99
00:04:42,960 --> 00:04:46,639
so does it mean that this huge whipper

100
00:04:46,639 --> 00:04:48,847
was harder than the slam

101
00:04:48,847 --> 00:04:52,194
it doesn't look like that right

102
00:04:52,194 --> 00:04:55,040
and to make sense out of all of this we

103
00:04:55,040 --> 00:04:58,639
need to define what does it mean harder

104
00:04:58,639 --> 00:05:00,880
what we measured is the peak force to

105
00:05:00,880 --> 00:05:03,600
the climber's harness and this peak

106
00:05:03,600 --> 00:05:08,080
force happens around this moment

107
00:05:08,080 --> 00:05:13,339
[Music]

108
00:05:13,440 --> 00:05:15,520
and if you look closely this doesn't

109
00:05:15,520 --> 00:05:17,759
look that bad

110
00:05:17,759 --> 00:05:20,000
and what gets our attention is actually

111
00:05:20,000 --> 00:05:23,039
the contact to the wall imagine if this

112
00:05:23,039 --> 00:05:27,280
wall would have been not overhanging

113
00:05:27,280 --> 00:05:30,160
then the peak force on the dynamometer

114
00:05:30,160 --> 00:05:32,320
to the climber's harness would read

115
00:05:32,320 --> 00:05:34,880
exactly the same but the slam to the

116
00:05:34,880 --> 00:05:37,600
wall would be much worse and that's by

117
00:05:37,600 --> 00:05:39,520
the way how most of the people sprain

118
00:05:39,520 --> 00:05:42,639
their ankles shortfall hard catch

119
00:05:42,639 --> 00:05:45,520
super quick slam into the wall so how

120
00:05:45,520 --> 00:05:47,919
hard the fall for the climber is will

121
00:05:47,919 --> 00:05:50,479
depend on two things first is the

122
00:05:50,479 --> 00:05:53,840
initial impact to the harness this

123
00:05:53,840 --> 00:05:56,000
that we measured to be around three to

124
00:05:56,000 --> 00:05:58,160
three and a half kilonewtons on hard

125
00:05:58,160 --> 00:06:02,160
falls let's test how three kilonewtons

126
00:06:02,160 --> 00:06:03,680
feels

127
00:06:03,680 --> 00:06:06,319
on the harness

128
00:06:06,319 --> 00:06:09,440
don't do this at home

129
00:06:15,520 --> 00:06:18,520
ouch

130
00:06:21,840 --> 00:06:24,160
told you not to do this at home

131
00:06:24,160 --> 00:06:25,759
listen learned

132
00:06:25,759 --> 00:06:28,160
falling on a single bolt on three

133
00:06:28,160 --> 00:06:30,160
kilonewtons of force

134
00:06:30,160 --> 00:06:34,560
can make an entire bolt come out

135
00:06:34,560 --> 00:06:35,600
of

136
00:06:35,600 --> 00:06:41,039
18 millimeters of shitty spanish plywood

137
00:06:44,000 --> 00:06:45,199
so

138
00:06:45,199 --> 00:06:47,520
the impact was

139
00:06:47,520 --> 00:06:49,280
okay

140
00:06:49,280 --> 00:06:51,759
but the landing on the ass was

141
00:06:51,759 --> 00:06:53,199
not so okay

142
00:06:53,199 --> 00:06:54,240
all right

143
00:06:54,240 --> 00:06:57,919
don't do this at home number two

144
00:06:57,919 --> 00:07:00,639
since i really want to experience three

145
00:07:00,639 --> 00:07:02,560
or three and a half kilonewtons of force

146
00:07:02,560 --> 00:07:05,120
to my harness so i can tell you

147
00:07:05,120 --> 00:07:06,800
how that feels

148
00:07:06,800 --> 00:07:08,800
i rigged another system

149
00:07:08,800 --> 00:07:10,160
which is

150
00:07:10,160 --> 00:07:12,400
hopefully not gonna end up like the

151
00:07:12,400 --> 00:07:13,680
first one

152
00:07:13,680 --> 00:07:15,759
this time it's very static but it

153
00:07:15,759 --> 00:07:17,440
doesn't matter

154
00:07:17,440 --> 00:07:21,120
i just want to feel it

155
00:07:22,479 --> 00:07:23,599
wow

156
00:07:23,599 --> 00:07:26,720
that was 3.8

157
00:07:26,720 --> 00:07:29,720
kilonewtons

158
00:07:30,319 --> 00:07:34,319
and actually that felt quite okay

159
00:07:34,599 --> 00:07:37,440
3.1 kilonewtons

160
00:07:37,440 --> 00:07:41,360
and i barely feel anything

161
00:07:43,280 --> 00:07:45,840
three and a half

162
00:07:48,000 --> 00:07:51,360
okay this was almost four kilonewtons so

163
00:07:51,360 --> 00:07:53,520
under three kilonewtons

164
00:07:53,520 --> 00:07:56,000
i don't feel anything between three and

165
00:07:56,000 --> 00:07:59,039
four i get a little but that's far from

166
00:07:59,039 --> 00:08:00,319
injuring me

167
00:08:00,319 --> 00:08:01,360
and

168
00:08:01,360 --> 00:08:05,440
my homemade climbing wall breaks at

169
00:08:05,440 --> 00:08:08,879
3.8 kilonewtons to default which would

170
00:08:08,879 --> 00:08:11,840
be around 2 kilonewtons to the climber

171
00:08:11,840 --> 00:08:12,720
so

172
00:08:12,720 --> 00:08:14,479
my homemade climbing

173
00:08:14,479 --> 00:08:16,879
wall is not for

174
00:08:16,879 --> 00:08:19,520
falling and the second thing that the

175
00:08:19,520 --> 00:08:21,759
climber will experience is of course the

176
00:08:21,759 --> 00:08:25,360
impact to the wall which as we saw might

177
00:08:25,360 --> 00:08:28,319
be problematic in fact let's zoom in on

178
00:08:28,319 --> 00:08:30,400
the big fall and watch it couple of

179
00:08:30,400 --> 00:08:32,879
times

180
00:08:36,640 --> 00:08:41,479
and now let's compare it to the gym fall

181
00:08:45,360 --> 00:08:47,920
so as you can see it's not that easy to

182
00:08:47,920 --> 00:08:50,640
tell which one was actually harder and

183
00:08:50,640 --> 00:08:53,680
it also depends a lot on climbers skills

184
00:08:53,680 --> 00:08:56,560
to absorb the impact with his legs as a

185
00:08:56,560 --> 00:08:58,399
climber you basically need to be like a

186
00:08:58,399 --> 00:09:01,279
cat when you hit the wall super soft and

187
00:09:01,279 --> 00:09:02,959
people who do a lot of baldering they

188
00:09:02,959 --> 00:09:05,120
tend to be much better because they fall

189
00:09:05,120 --> 00:09:07,040
on the crash pads a lot

190
00:09:07,040 --> 00:09:09,200
and falling on a crash but with stiff

191
00:09:09,200 --> 00:09:12,560
legs would probably kill you so the same

192
00:09:12,560 --> 00:09:15,040
applies to falling on ropes you want to

193
00:09:15,040 --> 00:09:18,080
absorb the impact as soft as possible

194
00:09:18,080 --> 00:09:20,080
and of course there are other factors

195
00:09:20,080 --> 00:09:21,920
that contribute to how hard you will

196
00:09:21,920 --> 00:09:24,399
slam to the wall for example jumping

197
00:09:24,399 --> 00:09:26,399
away or pushing yourself away from the

198
00:09:26,399 --> 00:09:28,959
wall as i talked in the previous episode

199
00:09:28,959 --> 00:09:30,160
or

200
00:09:30,160 --> 00:09:33,360
belaying in really hard ways in gym case

201
00:09:33,360 --> 00:09:35,839
we created a hard catch on purpose

202
00:09:35,839 --> 00:09:38,640
however on outdoors whipper the belayer

203
00:09:38,640 --> 00:09:42,480
was standing and doing nothing

204
00:09:48,399 --> 00:09:51,200
handbag

205
00:09:51,200 --> 00:09:53,279
and i have a separate video coming where

206
00:09:53,279 --> 00:09:55,279
i will show that standing and doing

207
00:09:55,279 --> 00:09:58,080
nothing creates much harder catch than

208
00:09:58,080 --> 00:10:00,959
pretty much any soft delaying method you

209
00:10:00,959 --> 00:10:03,839
can try so although this belay didn't

210
00:10:03,839 --> 00:10:06,720
looked hard it was definitely possible

211
00:10:06,720 --> 00:10:09,680
to make it much softer but this was

212
00:10:09,680 --> 00:10:11,839
actually perfect because i got the force

213
00:10:11,839 --> 00:10:14,560
to the climber on big whipper on hardish

214
00:10:14,560 --> 00:10:15,519
catch

215
00:10:15,519 --> 00:10:18,720
totally realistic scenario and that's

216
00:10:18,720 --> 00:10:20,480
actually not all

217
00:10:20,480 --> 00:10:22,320
in the following months i was going

218
00:10:22,320 --> 00:10:25,700
around and making a ton of experiments

219
00:10:25,700 --> 00:10:27,360
[Music]

220
00:10:27,360 --> 00:10:29,839
during which i recorded the forces to

221
00:10:29,839 --> 00:10:33,279
the climber on over hundreds of faults

222
00:10:33,279 --> 00:10:35,920
and even ryan sent me some clips of his

223
00:10:35,920 --> 00:10:39,120
to compare the datum

224
00:10:41,040 --> 00:10:42,320
oh

225
00:10:42,320 --> 00:10:44,320
oh that was better than wheaties in the

226
00:10:44,320 --> 00:10:45,440
morning

227
00:10:45,440 --> 00:10:50,160
i hit 1.14 i got 2.64 and the hardest

228
00:10:50,160 --> 00:10:52,700
fall i recorded was this one

229
00:10:52,700 --> 00:10:55,869
[Music]

230
00:10:56,800 --> 00:11:01,839
okay okay you saved me

231
00:11:02,160 --> 00:11:05,800
this is the hardest recording you've got

232
00:11:05,800 --> 00:11:07,440
3.60

233
00:11:07,440 --> 00:11:09,200
so in this case we were filming an

234
00:11:09,200 --> 00:11:12,240
episode of how to belay sketchy close to

235
00:11:12,240 --> 00:11:14,399
the ground falls

236
00:11:14,399 --> 00:11:16,720
the climber was clipping the second

237
00:11:16,720 --> 00:11:19,279
quick draw above his head and takes a

238
00:11:19,279 --> 00:11:22,279
fall

239
00:11:22,750 --> 00:11:28,079
[Music]

240
00:11:28,079 --> 00:11:30,160
so that's another sneak peek into the

241
00:11:30,160 --> 00:11:31,920
future what's coming on my channel and

242
00:11:31,920 --> 00:11:33,760
if you don't want to miss that i hope

243
00:11:33,760 --> 00:11:36,560
that you do youtube things and subscribe

244
00:11:36,560 --> 00:11:39,040
and click all of these bells and stuff

245
00:11:39,040 --> 00:11:41,680
but for now i can say that unless the

246
00:11:41,680 --> 00:11:44,800
climber is really really heavy

247
00:11:44,800 --> 00:11:47,519
or we are in some unlucky multi-pitch

248
00:11:47,519 --> 00:11:50,880
scenario which i haven't had time yet to

249
00:11:50,880 --> 00:11:54,000
experiment with creating a fall which

250
00:11:54,000 --> 00:11:57,440
would be harder than four kilonewtons

251
00:11:57,440 --> 00:11:58,959
to the climber

252
00:11:58,959 --> 00:12:02,320
is really really unlikely and that's

253
00:12:02,320 --> 00:12:04,560
really good to know because it just

254
00:12:04,560 --> 00:12:07,519
shows how great the climbing ropes are

255
00:12:07,519 --> 00:12:10,320
at keeping us safe as i've just

256
00:12:10,320 --> 00:12:13,200
demonstrated here four kilonewtons to

257
00:12:13,200 --> 00:12:15,839
climbers harness is not really something

258
00:12:15,839 --> 00:12:18,480
we should worry about unless of course

259
00:12:18,480 --> 00:12:20,320
it's accompanied by a

260
00:12:20,320 --> 00:12:23,040
slam to the wall and that brings me to

261
00:12:23,040 --> 00:12:24,880
the original question

262
00:12:24,880 --> 00:12:28,639
can i snap this very worn out rope on

263
00:12:28,639 --> 00:12:31,440
the realistic climbing fall

264
00:12:31,440 --> 00:12:34,000
or now i can rephrase the question can i

265
00:12:34,000 --> 00:12:37,360
snap this rope on forces below 4

266
00:12:37,360 --> 00:12:40,240
kilonewtons to the rope and the answer

267
00:12:40,240 --> 00:12:43,839
to this surprised me a lot i had a

268
00:12:43,839 --> 00:12:45,519
chance to hang out with mamamoo

269
00:12:45,519 --> 00:12:47,920
engineers and test this

270
00:12:47,920 --> 00:12:50,639
and also ask pretty much any question i

271
00:12:50,639 --> 00:12:53,360
wanted and man that was super

272
00:12:53,360 --> 00:12:55,839
interesting so i recommend to not miss

273
00:12:55,839 --> 00:12:58,800
the next episode and until then i'm

274
00:12:58,800 --> 00:13:01,120
gonna leave you with somebody who really

275
00:13:01,120 --> 00:13:02,880
likes challenges

276
00:13:02,880 --> 00:13:05,880
okay

277
00:13:07,120 --> 00:13:10,399
that left hand is 29.

278
00:13:10,399 --> 00:13:12,720
no i think sitting is better it's all

279
00:13:12,720 --> 00:13:14,410
about technique

280
00:13:14,410 --> 00:13:18,010
[Music]

281
00:13:18,160 --> 00:13:23,279
it's better it's 8 68 now

282
00:13:23,360 --> 00:13:25,519
okay pressing as hard as you can with

283
00:13:25,519 --> 00:13:27,510
one hand

284
00:13:27,510 --> 00:13:34,080
[Music]

285
00:13:34,399 --> 00:13:36,880
he's going slow

286
00:13:36,880 --> 00:13:39,120
he's he's weaker than i

287
00:13:39,120 --> 00:13:40,240
yeah

288
00:13:40,240 --> 00:13:42,480
really

289
00:13:44,000 --> 00:13:45,440
what

290
00:13:45,440 --> 00:13:48,399
how how much do you do i don't say it ah

291
00:13:48,399 --> 00:13:50,160
and to make this competition a little

292
00:13:50,160 --> 00:13:53,040
bit more fair i decided to split it into

293
00:13:53,040 --> 00:13:56,480
1 000 for guys and 1 000 for girls and

294
00:13:56,480 --> 00:13:59,120
to make it even more interesting girls

295
00:13:59,120 --> 00:14:01,519
can win both categories of course if

296
00:14:01,519 --> 00:14:03,920
there is a girl who is stronger than

297
00:14:03,920 --> 00:14:06,320
the guys

298
00:14:11,440 --> 00:14:13,920
not better yeah you can grab in any way

299
00:14:13,920 --> 00:14:14,959
you like

300
00:14:14,959 --> 00:14:16,880
any recommendation

301
00:14:16,880 --> 00:14:19,600
oh no it's a competition i don't give

302
00:14:19,600 --> 00:14:20,350
any hands

303
00:14:20,350 --> 00:14:25,600
[Music]

304
00:14:25,600 --> 00:14:28,560
everybody tries to go slow first what's

305
00:14:28,560 --> 00:14:32,880
this i'm so much better

306
00:14:33,310 --> 00:14:35,360
[Music]

307
00:14:35,360 --> 00:14:36,880
oh

308
00:14:36,880 --> 00:14:41,240
the good technique was funny

309
00:14:44,720 --> 00:14:47,680
it's going to be worse

310
00:14:48,079 --> 00:14:49,279
yeah

311
00:14:49,279 --> 00:14:51,839
50.

312
00:14:55,760 --> 00:14:58,160
where is the power screen oh my god oh

313
00:14:58,160 --> 00:14:59,839
my god

314
00:14:59,839 --> 00:15:03,360
oh you have seventy

you have seventy even the dog

316
00:15:05,040 --> 00:15:07,440
congratulations

317
00:15:07,440 --> 00:15:10,000
or no boxing techniques right

318
00:15:10,000 --> 00:15:13,120
watch out my mind

319
00:15:18,720 --> 00:15:23,440
oh it works the boxing technique works

320
00:15:23,760 --> 00:15:25,920
it's all about technique you like the

321
00:15:25,920 --> 00:15:29,440
boxing kidneys somehow

322
00:15:29,680 --> 00:15:32,720
you want to try boxing

323
00:15:38,839 --> 00:15:42,880
technique it's my best

324
00:15:45,040 --> 00:15:46,639
by the way did you notice that this

325
00:15:46,639 --> 00:15:49,279
episode had no annoying ads

326
00:15:49,279 --> 00:15:54,440
this is thanks to people like this guy

327
00:16:00,030 --> 00:16:03,159
[Applause]

328
00:16:03,920 --> 00:16:06,000
