Science fillosuffee

The amount of people I've met who were willing to answer a seemingly stupid question is pretty hopeful. Like we all know the question is rather idiotic, but it's worth answering anyway.

My sister has a phd in chemistry, 12 patents, and after being an actual scientist now works as an exec for a company that creates additives for motor oil...and one time as a seventeen year old she blew up a balloon with her own lungs, let it go, and then asked me why it fell instead of flying away.
