Water Balloons in Space!

Space scientist Don Petit shows us what happens when you pop a water balloon in space. With all his talk about pancakes and potatoes, it just made me hungry for potato pancakes. And then he says, "You can't do this too many times." I thought yeah, because you've got a real mess to clean up there in the space station, but he really meant that it's so much fun you CAN'T do this TOO many times. (via mental_floss)
