WOW! Canada can be so proud of that space-hoser conducting that scientific experiment. And this was created by 10th graders? Boy has high school science has really progressed over the years.

Oh well, take off Eh!

Actually, it is a deceptively simple question that has broad implications for zero/micro gravity systems. If water from the wash cloth sticks to his hands, think about what happens to water vapor that condenses on surfaces. What happens if that condensation builds over time? Oxidation? Short circuits? Mold? All pretty bad things in a closed environment far from a hardware store.

And since you think it is such a silly question, why don't you tell us all what surface tension is and what causes it. Why does the meniscus on water tend to flow up the side of a container while a mercury meniscus tends to be down the container.

Heck, just tell us why water is wet.

(I'll give you a hint: it is a type of bonding)

I could care less is my answer.

No need to get all defensive and jumpy. It appears your surface tension coupled with a large buildup of condensation is causing water vapor to build up on your neurons and synapses. This in turn is causing you to drop well below the max 100 hz processing power of your neuron operational rate. Suggest you ease her back a bit as this process cycle may hinder your “Long-Term Potentiation.”

Since you "could care less" (suggesting you DO care), the answer is Hydrogen Bonding. Understanding how water droplets behave is kinda important when designing some de/anti ice systems.

Really though, it is a cool test. Even though you may not care, it still matters. No reason mocking high school kids with a pretty neat idea for an experiment.
