00:00:00.940 --> 00:00:02.471
When you go to the bathroom on earth,

00:00:02.471 --> 00:00:04.957
you're relying on gravity...pretty, pretty heavily

00:00:04.957 --> 00:00:08.971
Imagine if you're half way done and somebody shut off gravity

00:00:08.971 --> 00:00:13.082
It'd be a mess and you'd float of the toilet

00:00:13.082 --> 00:00:17.063
So, when we designed our space toilet

00:00:17.063 --> 00:00:19.349
first to a seat belt on it, to hold you down

00:00:19.349 --> 00:00:27.020
and then, we decided to separate solids and liquids because it is easier to store that way

00:00:27.020 --> 00:00:32.057
So, we just have tube that you pee into, and have air pulled to the tube

00:00:32.057 --> 00:00:33.682
so it's not a big deal

00:00:33.682 --> 00:00:35.338
For the women, there's a cup that fits-up against them,

00:00:35.338 --> 00:00:38.276
For the guy , it's just a little tunnel, you just pee into the stupid

00:00:38.276 --> 00:00:40.027
it goes into a sewage tank

00:00:40.027 --> 00:00:45.293
But the solids that come out of your body ,

00:00:45.293 --> 00:00:46.858
that's a harder problem to solve

00:00:46.858 --> 00:00:48.511
And it's an important medical one,

00:00:48.511 --> 00:00:50.476
because on Earth everything falls on the floor

00:00:50.476 --> 00:00:52.377
But in space it's gonna float around

00:00:52.377 --> 00:00:57.574
So it'll really make you sick

00:00:57.574 --> 00:01:00.755
If you re-ingest something that came out of your body

00:01:00.755 --> 00:01:02.751
it will really make you sick

00:01:02.751 --> 00:01:04.372
And we can't afford to get that sick

00:01:04.372 --> 00:01:06.182
So we designed a toilet that,

00:01:06.182 --> 00:01:08.194
instead of gravity pulling everything into the toilet,

00:01:08.194 --> 00:01:10.101
it has air flow

00:01:10.101 --> 00:01:11.555
There's air pulled down into the toilet

00:01:11.555 --> 00:01:13.035
-- Sort of windy when you're sitting there

00:01:13.035 --> 00:01:14.656
But it pulls everything out of your body

00:01:14.656 --> 00:01:16.746
Everything that comes out of your body

00:01:16.746 --> 00:01:18.774
gets pulled down into the toilet by the air

00:01:18.774 --> 00:01:23.433
and then in the storage tank we just expose that to the vaccum of space ,

00:01:23.433 --> 00:01:25.584
so it basically just freeze-dries everything

00:01:25.584 --> 00:01:27.427
So it killes all the bacteria

00:01:27.427 --> 00:01:29.193
so there's no smell

00:01:29.193 --> 00:01:31.353
And then we store it

00:01:31.353 --> 00:01:33.870
And then when we have a whole bunch if stored

00:01:33.870 --> 00:01:35.789
we put in a little unmanned supply ship

00:01:35.789 --> 00:01:38.799
and then we undock it and then it burns up in the atmosphere

00:01:38.799 --> 00:01:45.888
So the next time you see a beautiful shooting star going across the sky

00:01:45.980 --> 00:01:48.463
that's what it might be
