The question is if you get a cloth dripping wet
without gravity and your wring it out,
what’s going to happen?
What will happen to a wrung out cloth?
So, and had to use equipment that was here
on board the space station?
We may have the coolest washcloths ever
here on the space station, I’m going to show you. 
Here’s one of our washcloths
and it’s packed in,
it’s put down under this little tiny hockey puck
so that it saves space,
but when you open up a hockey puck
and you pull out your washcloth,
this is the one I’m going to use
for the experiment today
and so when you open up your hockey puck
and turn it into the wash cloth
that was compressed
in a great big vise somewhere,
okay, so here’s my wash cloth,
like a magic trick
and now, I’m going to get this soaking wet
and then we’re going to see what will happen 
when we wring it out.
Meredith and Kendra suggested that
I did this in a bag,
but bags don’t know water in space.
So instead, I’ve filled a water bag. 
This has drinking water in it
and I’m going to squirt a bunch of water
into this washcloth.
Okay, so here’s a soaking wet washcloth,
I’ll get the microphone
so you can hear me while I’m talking
and now let’s – let’s start wring it out.  
It’s really wet.
It’s coming to the water.
The water is all over my hands.
In fact, it wrings out of the cloth into my hands
and if I let go of the cloth carefully,
the water sort of sticks to my hand.
Okay, so the experiment worked beautifully
and the answer to the question is
the water squeezes out of the cloth 
and then because of the surface tension  
of the water,
it actually runs along the surface of the cloth
and then up into my hand,
almost like you had jell-o on your hand 
or gel on your hand and it will just stay there,
a wonderful moisturizer on my hands,
and the cloth doesn’t really unravel itself.
It just stays there
floating, like a dog’s chew toy, soaking wet.  
A great experiment, it worked perfectly.
Meredith and Kendra, congratulations, great idea.
