Four dice are stacked in a small column and a small tube is shown to only just fit over the dice. But when the tube is lifted, the number of dice doubles, and the column is twice the size. This really looks like real magic!
Cover a stack of dice with a small tube, yet when you lift off the tube, the number of dice grows and grows until you have double the number you started with.
A surprising gimmick that is built into the tube makes this startling effect possible.
At the end of the performance, you can hand out the tube and the dice for a thorough examination.
