Because doing physics in space can produce some rarely-seen results, NASA astronaut Don Pettit conducted experiments on video while aboard the International Space Station in 2011/12. In this Science Off the Sphere video, he pops balloons in microgravity. Space Balloonacy!
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?
There are Science Off the Sphere videos galore at PhysicsCentral.com.
