WITH THE HELP OF ONE HAND: For each player (there must be not more then 4 of them) there is a heap of many small and some big objects. The task is to carry all of them in one hand to the distance of 5-7 meters being blindfolded. The players mustn't hold the objects with the other hand or drop them on the floor. The player who covers the distance the first becomes the winner.
