Wikipedia: Dice Staking
Dice stacking is an individual leisure activity in which players scoop dice off of a flat surface with a dice cup and then set the cup down to build a vertical column of dice. Various dice arrangements, colors of dice and scooping patterns allow for many degrees of complexity and difficulty.
Here is my description of Dice Staking - A radical hobby with magic and witchcraft involved. Players make dice disappear with a cup....and then they make the dice magically reappear in different patterns.
