Slinkies, terminal velocity, and Bernoulli, oh my!

Terminal velocity sounds like deadly force, but it's actually another cool point to consider about how marvelously our world works.  My crazy thank-you  about it?   I keep imagining anything like hailstorms or even raindrops would be somewhat more...painful without those air molecules and low pressure/high pressure influences creating drag to slow things down.   Here's the video that LV suggested.  Disclaimer: obviously a very secular Youtube channel.  I have no control over the ads or suggested videos that pop up.  Yeah, robot weirdos, I am talking about you! Disregard and hit the video.

and here's the levitating slinky.

Hopefully I can get out our own levitating slinky shots up soon!


Next up:  Bernoulli and fluid forces! Can you hover a ping-pong ball over a hairdryer?
