A bottle of grape juice is covered with a cylinder, while a peg glass is covered with a similar cylinder. Some magic words are spoken, and when the cylinders are lifted, the two have changed places!
This is repeated several times. Suddenly the peg glass vanishes, only to discover a bottle of milkshake is found in its place! Thereafter, several bottles of different juices (mango, pineapple, and orange) are produced from the cylinder, one after another, which ultimately covers the entire table with TEN bottles! And as a “prover,” liquid is also produced from two of the bottles.
Looks magical, and can be performed in a comedic fashion if desired!
