Oscillations of a fluid in a pipe (kind of like a drinking straw)

What's interesting is that the deeper the straw is in the water, the more oscillations you'll have because the pressure difference is higher!

Instead of saving for my kids' college, I make videos using the money I would have saved.

The thought is it will help educate the world as a whole, and one day generate enough revenue to pay for their education. Until then if you appreciate what you've learned in this video and the effort that went in to it, please SHARE THE VIDEO!
