Pop a water balloon in space?

[pygmypiranha]

Did you ever wonder what it would be like to pop a water balloon in space?

Scenario:
Experimenters burst water balloons in the low-gravity environment produced aboard a NASA Glenn DC-9 aircraft.

The ultimate water balloon fight. You can just bag up the water and throw it back.

Technically you mean popping a water balloon in zero gravity. Space is a vacuum and therefore the balloon would pop instantly and the water would boil into vapor and disapate. Depending on where the sun is in all this, the rubber balloon part would either freeze or burn up.

Wow, I've never met a physics nazi before.

No Water For You!

[Max Power]

The water would freeze in space.

imagine popping a condom in zero-g

The water would freeze in space.
Ha, physics nazi pwnage.
Some of the coolest video I've seen in a while.

Actually due to no pressure, the boiling point is severly reduced and the water boils.

[Nachofunk]

This is proper balloon popping.

I was under the impression that asteroids/comets contained frozen water, though.
Elaborate?

[Nachofunk]

It would probably be better explained by someone who has studied physics further, but I would surmize that frozen water is in the asteroid. Meaning it is held under pressure by gravity and other elements keeping it from being exposed to vacuumus space.

Heat is a measure of energy and is affected by pressure. With a complete lack of pressure the boiling point of water would fall significantly so that even though it is extremely cold the water still enters a vapor state.

This has been shown in experiments where a man made vacuum (which still doesn't quite match up to the complete vacuum of space) brought water to boiling at less than room temperature.

Mass attracts mass, the water particles in the asteroid clump togehter, forming enough gravity to sustain solid mass.....


....derr!

Thanks, I feel enlightened now. :)

Well. . . . . . I like cheese

Wow, I could really go into this, but I will leave you with this food for thought: Spheres are unique in respect to gravity. Earth, for an example, like other spheres, have zero gravity in the center, which would be the inner core. Think of how density and depth relate to that, thus there is a geothermal gradient. Gravity does weird things.

Gravitational Constant (as derrived in the 1700's) multiplied by one mass which is multiplied by the other mass it is attracted to and divided by the distance will produce the amount of force present between the two objects.

Another point: all substances have 2 boiling points, one at extremely high temp and one at extremely low temp. This low temp boiling is usually a result of sublimation.

You're so cute when you get excited about rocks.
Never knew gravity tied in so closely with geology.

Physics ties in very closely along with calculus, chemistry, paleontology
