Thus the trick Newton's Nightmare.

Non-Ferris metal acts like a mirror to magnetism.
It reflects the magnet's own magnetism back to itself.
So it's "like" dropping a magnet into a magnetic tube with the same polarity, which causes it to repel.
Which causes gravity to have a hard time pulling it down.

Other than Newton's Nightmare, Mikames chop cup takes advantage of this.
So does a non-commercial effect by Brian Nordstrom, which I can't say what but it's really really cool.

This is a great little effect. I work in science communication and use this it a lot. Its a greta example of a magic effect using science. I use it on sonmthing we do called magic of science-science of magic. If you want to know more about the science its called Lenz Law. Check it out. There a few kits on the market but this is one of the best. http://www.grand-illusions.com/acatalog/Lenz_s_Law_Demo.html

Here's a good video that explains the effect:

Hi Everyone,

I also released a trick called "The Field Sobriety Test" in 2004 (http://www.themagiccafe.com/forums/viewtopic.php?topic=59262&forum=109). Lots of fun!!!! I may have a few sets left. PM me if you are interested!

Enjoy the Search!

Thanks that was very interesting.

I'm still waiting for someone to produce an electrically-conductive clear plastic tube for this effect.
