00:00:00,000 --> 00:00:26,600
Dramatic Music

2
00:00:26,640 --> 00:00:28,060
Now were doing this in part for fun, but

3
00:00:28,090 --> 00:00:30,160
really below all of this is engineering

4
00:00:30,200 --> 00:00:32,610
and science type of data. 80% of the

5
00:00:32,650 --> 00:00:34,370
work here is going to be science, but

6
00:00:34,410 --> 00:00:35,960
20% of this work is going to be fun for

7
00:00:35,990 --> 00:00:38,110
the astronauts, unscripted fun that they

8
00:00:38,140 --> 00:00:39,860
can use at lunch time whether they’re

9
00:00:39,890 --> 00:00:41,680
drinking cocoa or peach mango

10
00:00:41,710 --> 00:00:43,680
smoothies or whatever, or espresso, ok

11
00:00:43,720 --> 00:00:44,920
those are the kinds of things that we

12
00:00:44,950 --> 00:00:46,100
expect to be fun but theres really

13
00:00:46,130 --> 00:00:47,760
science underneath all of this stuff too.

14
00:00:47,800 --> 00:00:49,600
Don Petit demonstrated an early version

15
00:00:49,640 --> 00:00:51,340
in cooperation with us. It was actually

16
00:00:51,370 --> 00:00:52,920
patented but there are new items in this

17
00:00:52,950 --> 00:00:54,510
design that make it unique so there is a

18
00:00:54,540 --> 00:00:55,840
second patent coming. They take a

19
00:00:55,880 --> 00:00:57,730
drink bag now from the dispenser, any

20
00:00:57,770 --> 00:00:59,650
drink that they wish to do and then they

21
00:00:59,690 --> 00:01:01,500
dispense it into the cup. It wicks inside

22
00:01:01,530 --> 00:01:03,400
the cup and is stable inside so it holds in

23
00:01:03,430 --> 00:01:05,630
there like as if gravity was holding it but

24
00:01:05,670 --> 00:01:07,390
it’s surface tension not gravity. When

25
00:01:07,420 --> 00:01:09,420
they go to drink, they make a capillary

26
00:01:09,450 --> 00:01:10,870
connection and then they continue to

27
00:01:10,900 --> 00:01:12,880
drink normally but it’s surface tension t

28
00:01:12,910 --> 00:01:14,620
that’s bringing liquid to the face not

29
00:01:14,650 --> 00:01:16,250
gravity, so it’s not being poured into the

30
00:01:16,290 --> 00:01:17,760
mouth, it’s being drawn in by surface

31
00:01:17,790 --> 00:01:19,480
tension forces. We’ve since found out

32
00:01:19,510 --> 00:01:21,080
that if you make a reusable cup, you

33
00:01:21,120 --> 00:01:22,540
can save all kinds of volume in terms of

34
00:01:22,570 --> 00:01:24,070
the bags that they use in Space Station.
