Popping Water Balloons in Space
Everybody likes popping water balloons on Earth. But what happens when you pop a water balloon on the International Space Station, without gravity?
So here's the test -- think about what you think will happen in this scenario. Will the water stay exactly where it was pre-pop, or will it move? If you think it will move, why would it move? In this video (including slow motion), astronaut Don Pettit pops a series of water balloons while in space, and shares the results.
