Chris: My name's Chris Gundy, and I'm 16 years old.
Max: I'm Max. I'm 16, too.
Louis: And I'm Louis, and I'm also 16.
Chris: We're entering an experiment
based on capillary actions on YouTube Space Lab.
We're all good friends, so most of all,
it's just a bunch of good fun.
Max: Louis.
Louis: Oh, what's this?
Chris: So we wanted to find out,
does microgravity change the properties of capillary action?
Louis: Now, capillary action is a phenomenon
in which liquids, such as water or alcohol,
move up a tube generally against gravity.
And it's well-documented how this works on Earth,
but we want to find out how this would work
in a microgravity environment.
Yeah, we were thinking if--
Gs in space is gonna be much smaller, isn't it?
Yeah.
Which means the height is gonna be a lot bigger.
If we have tubes come into water...
and if we have different diameters,
it's gonna go up higher.
Max: We need to contain that.
Louis: Yeah, we need to contain it,
because otherwise it's gonna be floating around, isn't it?
Max: Ding!
I'll hypothesis
is the height of the fluid in the tube
will rise much higher and at much greater speed
than it would on Earth.
We also project fluid can move up and down the tube,
which is also interesting.
Chris: The water should go up here.
Oh, wow, that's cool.
Louis: Yeah, look how far it's already gone.
If capillary action works in space as we expect,
then our expected results are that the water will flow
much higher than it would on Earth
and possibly much bigger as well,
which could have interesting results
for engineering in space.
Chris: What on Earth?
[laughter]
all: Vote for us.
