>> Is there an experiment you've thought of since
your last mission?
>> Oh, this is from Laura Austin?
>> LA is my lady.
That's what, that's her call sign for Twitter.
>> Well, but from Austin you would think that'd be
>> You never know.
So is, but this one's for you, Don.
Is there an experiment you have thought of since your
last mission that you would like to try in
>> Oh, man.
I'm going to have to--
>> A million of them.
I've got a running list of experiments that I want to
do for my next flight.
And there's several kinds of experiments.
There are programatic experiments.
These are well-planned, well thought out
experiments that PIs on the ground orchestrate and
we do them like glorified graduate--
>> These principal investigators, we call
This is the main scientist or engineer that thought
>> Oh yeah.
>> Oh, yeah, yeah.
And if they were on orbit with us, they'd be "PI in
[ Boing Sound ]
But anyway, so we have those experiments and
>> I think we're going to keep him.
>> And [laughs] or you need to send me off the
[ Laughs ]
And then we have some experiments we could think
up just because we're there and we can.
And so the kinds of experiments that I will
highlight are what kind of experiments would I like
to do in my off-duty time using the resources there?
And I think I would do more experiments dealing
with static charge because static charge force says,
you know, scuff your feet across the carpet and then
the little spark jumps out from your fingertip.
>> Or like rubbing a balloon, you know.
>> Oh, and stick the balloon on--
>> Right, that kind of static electricity, yep.
>> Yeah, that kind of static electric.
They, those forces are weak compared to gravity,
and so you can repeat those experiments in a
weightless environment and they make wonderful
>> So school kids actually sent up an experiment like
that for us and what they were doing down on the
ground was that they were taking a piece of rubber
and they, like rubber tubing.
Just stretchy tubing.
And then they would take like a nylon stocking or
something and they would rub the tubing and so it
would be electrically charged and they'd hold it
next to a faucet and the faucet would be just like
not a big stream, but a little stream.
And when they held it next to the little stream--
>> Oh, the stream would be diverted.
>> It's bent, right?
So they wanted to know what would happen up on
the space station.
So Ron, Garrin, and I took this tube, stretched it
across the Japanese Experiment Module, got it
all statically charged--
>> Oh, that's just one of the rubber exercise
>> Exactly, yep.
>> We stole it from the exercise place.
So it's stretched across, got it statically charged,
and then took a drink bag and squirted a drop of
And so if my hand here or my arm is the tubing, this
water went and it went towards the tubing and it
wanted to keep going because, you know, it has
It wants to go, but then the tubing that's charging
it brought it back and it just kept orbiting and
orbiting and orbiting.
>> Oh, cool.
>> It was the coolest thing.
It was great.
