Borrowing two different bills from a spectator, you fold each bill into eighths. Then, simply by touching the two bills together, they visually fuse into one bill. That's right, the two halves of the bill are made up from the two bills you just borrowed from the spectator. This hybrid bill is handed to the spectator for complete examination. You then proceed to rip the bill in half, ending up with one of the original bills in each hand. These are immediately given back to their owner.

This isn't just another bill switch:

In fact, you can't really call it a bill switch at all. Hybrid feels just like a switch but from the audience's perspective, you're not transforming one bill into another... you're visually melding two of their bills into one unit, simply by touching them together. That's pretty amazing stuff.
