The Dice Atomizer - Two Magic Tricks In One - Great For Kids
A clear capped container with a black die inside is given one quick, small shake. Right before their eyes the die disintegrated into eight tiny colored dice!
Also, and this is my favorite, the die can be changed from black to white. A quick, visual effect. No sleight of hand or practice needed. You'll be doing this trick as soon as you take it out of the box. Complete with all the dice, container and detailed instructions.
