How does the floating card work with no magnets, wind, thread, plastic, etc.!!?

I dont want to buy it at all on the internet, cause i dont have an acoount. Ive been a magician for four years and cant find it out!!

Nothing can float without support, so your kind of out of luck there.

But go to ebay and look up the "humming bird card". I bought this trick and it works GREAT, its not expensive, complex, or to difucult, but very convincing and ingenious.
