This problem is more difficult than it appears. One one side you have rotational inertia to deal with. On the other you’ve got fluid shear. I bet you can’t get this right. If you don’t, please subscribe to help fight the epidemic of everyday ignorance.

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.
