My dad had one of those but without the motor. I like the ones that don't have any point of contact with the ground at all. I have one that you have to spin like a top to get it to float and it is quite difficult to start and it obviously slows down and stops in a minute or so. You can buy more modern ones that have a motor that keeps spinning - and float ...[text shortened]...

I am sure I read somewhere that stable leviation without motion was impossible. So how does this work?

[b]Here is one where you use bismuth crystals that do the same thing with no electronic tricks:
But it does require something above it.[/b]
