Money Printer by Mikame - Trick

EFFECT

Pure quality sets this apart from all other versions of this classic!
A wide tape moves between two rollers arranged on upper and lower axis.
Two knobs are used for turning the rollers.

Feed dollar-bill-sized slips of blank white paper into one side of the rollers, and REAL dollar-bills come out the other side.
Borrow a dollar from a spectator, run it through the money printer and a blank piece of paper appears. Apologize, and hand the paper back to the spectator.

Will work with foreign money!

Insert a blank piece of paper, turn the knob, and a dollar slips out the other side.
Now borrow a dollar from the audience, insert it into the printer, and a five dollar-bill falls out.
Put in the five, and a ten dollar-bill comes out.

Now , take the piece of paper from the audience member whose dollar you have already changed, insert it into the printer and his dollar appears at the other side.
