Surface tension wins – Water balloons in space

by Stephanie Chasteen on November 20, 2008

Here’s a great video of what happens when you pop a water balloon in space.

This is a nice clear lesson about surface tension and the war between different forces. When you take away gravity, then surface tension is able to hold together a much larger blob of water. It no longer has gravity trying to pull the water blob apart and then air drag breaking it up into droplets.
