Watch as astronaut Chris Hadfield shows you how to wring out a washcloth in zero gravity.
Producing a good whiskey is very much a science. The mix of ingredients react in complex ways to make the special flavors, so when the question arose whether zero gravity might change the reactions, the scientists on-board the International Space Station were up to the task of finding out.
The majority of us will never experience zero gravity. Design firm BRC Imagination Arts wants to change that with a $50 million roller coaster that'll let riders experience being weightless — for eight seconds.
When you live in zero gravity, the differences between walls, ceilings, and floors is irrelevant, because unlike on Earth, every surface can be fully utilized. But when you try to recreate that scenario in an environment bound by gravity, you're bound to run into a few problems.
