Cool video demo

It's about 2 minutes long, with a surprising/interesting end result.

"This is a video of a demo of laminar flow at low Reynolds number, R=0.2, which I did in class today."

EDIT: Courtesy of Goosemaster. Thank you! :)

What a cool thing for you to do! Thanks so much, Goosemaster. :)

The laminar flow demo was set up for the undergraduate class he teaches. Instead of only lecturing, he does a lot of demonstrations/experiments in class. I think that I would have enjoyed my undergraduate physics class much more if I'd had him as a professor, as he's very passionate about what he teaches.

One time, his family purchased a La-Z boy chair and placed it atop their station wagon to drive it home. His father adamently refused to tie it down, insisting that friction alone would keep it in place. Thankfully, it did!

Still, you might ask him if he might give you some in-home tutoring at a discounted rate...;)

wow. talk about practicing what you preach. I tie down things based on a mathematical model know as the "I don't really know if it might happen, but I am not about to find out" model:D

A famous experiment involving laminar flow uses two concentric glass cylinders with the gap filled with glycerin. A drop of ink placed in the fluid. When the outer cylinder is turned, the drop is drawn out into a thread that eventually becomes so thin that it disappears from view. At this point the ink molecules are said to be "enfolded" in the glycerin. If the cylinder is then turned in the opposite direction, the thread reforms and then becomes a drop. This experiment is typically used to show implicit order, but also nicely demonstrates the properties of laminar flow.

that's freakin cool.. i'm gonna send it to my brother (who's taken fluid dynamics classes and the like, im sure he'll appreciate it much more)
