MANICOLOR

The magician shows a scarf, which can be examined by your audience. The magician inserts the scarf into his previously shown empty hand, and it comes out of a different colour on the other side of the hand!
The colour change is progressive, the scarf changes as the magician pushes it into his fist!
At the end, the scarf can be given to the exam!

A great classic of prestidigitation!

Supplied without the scarves (to get some, see Related Product below).
