0:00For most of us, our best ideas come to us in the shower, or at least that's how I

0:04tend to get video ideas, anyway. But not today - I couldn't think because I kept

0:08getting attacked by my shower curtain, which obnoxiously billows inward while I'm in there.

0:13I thought it was happening because the hot water warms the air in the tub,

0:16which would then rise, causing cooler air from outside the shower curtain to push inward.

0:20But when I tried showering with cold water, the exact same thing happened.

0:25So I dug into the research and found that it's not the temperature, but instead,

0:29the air pressure in the shower. According to a twenty year old scientific paper that, believe

0:34it or not, tackled this problem by designing a computer simulation of water in a shower,

0:39as water flows into the tub, it basically pushes air out out. As that air rises,

0:44it swirls, creating a weak vortex, a showernado, a hurriclean - that tugs on the curtain from the

0:50inside. Which is fascinating - I guess I did get a good idea from this shower after all!
