a top that spins for eight hours

a very long time ago i had a top somewhat like this one . . . i've seen and tried all kinds since then . . .


here's the physics of tops.
over at "i want one of those dot com" whose mantra is "stuff that you don't need but you really, really want" there's a top that the manufacturers claim can spin for up to eight hours without stopping. holy moley! it's a bit expensive - i figure that with shipping you're looking at over twenty dollars but what a cool toy!!! have a look!
