"Cool" Möbius
« on: July 12, 2013, 08:20:22 AM »
"Cool" superconducting magnet on a Möbius strip.

We are at the very beginning of time for the human race. It is not unreasonable that we grapple with problems. But there are tens of thousands of years in the future. Our responsibility is to do what we can, learn what we can, improve the solutions, and pass them on.
--- Richard Feynman (1918-1988)

How come I never knew about the slow fall effect of a magnet through a copper pipe?  I'm glad he demonstrated that because I can actually try it myself - I'm going to have to show that to the kids.

Awesome!

Guy also has some big kahunas pouring liquid nitrogen without wearing gloves or much in the way of protective gear. Yikes! Talk about steady hands. :tellme:

I saw a similar video a while back - I *think* it was posted here on dc, and I *think* it used the same principles, but not sure.
Anyone else remember?

  Yep, showed a steel ball or something dropped through a pipe that took a long time to exit.

Hehehe! That's a good experiment to do! The 2 or 3 thousand magnets needed for the mobius strip make it a tad on the $$$ side. :D Would be nice to have the extra $$$ laying around for that one too though! :D
