Multiplying bottles (10)

The magician tells about the famous bottle and glass trick and shows 2 yellow sleeves. He picks them up and under one state a glass under the other one (martini) bottle.
He covered the tubes again and do this trick pasee de Passe (the glass and bottle exchange several times of place).
But if the magician's sleeve each time accidentally drop somewhere else and lifts, appears a 2nd bottle. Then a 3rd, 4th, etc. until there are 10 bottles!

The bottles are made of aluminum and nicely labeled so they look like real bottles. The effect can be around and show works very simply.

A classic!
