A plastic box, spike, and 6 different color blocks are shown. The
blocks are placed in the box and are secured with the long
spike and the lid is closed. The blocks are visible through the top of the box. The spike is removed and the blocks are dumped onto a
table. Two of the blocks are selected by the spectator and the blocks are placed in the box again and secured by the spike. When the box is opened the selected blocks fall out of the box while the other blocks remain secured by the spike.
