Dream Bag

Magician shows an empty paper bag to the audience. He reaches inside and removes a red silk. He then removes a clear box containing two flowers. Once again he shows the bag empty then reaches in and this time removes a yellow silk followed by a box containing two flowers. This is repeated a third time with a blue silk and flowers. The bag is obviously too small to contain the three boxes but that's exactly what happens!
