You will need a blindfold,2 big bowls, a bag of cottonballs and a spoon for each contestant or you can have one set and guests take turns competing (This is usually the most fun).

The player sits ,blindfolded, with both bowls within reach. The bowls have about 1-2 feet between them. One of the bowls is filled with cottonballs (you'll want to make sure beforehand that they aren't clumped together). The guest is given 30 seconds to tranfer the cottonballs from one bowl to the other using only the hand with the spoon. It is harder than it might seem, as the cottonballs are effectively weightless. The guests often take great scoops of nothing but air and are amazed at how few cottonballs they have by the end.

For this game, you can either have 2 guests at a time compete against each other to see who gets the most cottonballs transfered in the given time, or you can have them compete individually for the best all-round score.
