Dice stacking is the art of using a cup to stack dice. There is no trick, but a scientific principle, inertia. The dice are first picked up by the cup, and because of the motion of the cup resist movement like a bucket of water swung around. As a result, the dice stack inside the cup and slide around as if they were a single mass.
Step 1: What you need
- A cup
- Heavy casino dice / standard dice / rounded-edges dice
- Speed stacks cup / yahtzee cup / short plastic cup
Step 2: How this works
See below for 2D picture example
Step 3: Picking up the Dice
First, approach the dice at a 45 degree angle. Sharply switch directions as you strike the dice, as it rises to the top, hold the cup at an almost 90 degree angle. Repeat this process until all the desired dice are in the cup. Its similar to cradling a lacrosse ball. For reference, look at my video on the introduction.
