Hatching Dinosaur Egg

Similar to hot potato or time bomb, all the players stand in a circle. One
player is handed a water balloon, a real egg, or something else round. The
music starts and the balloon/egg (a.k.a. dinosaur egg) is passed to the next
boy. No one wants to be left with the dinosaur egg, because that boy is out
of the game. Continue playing until there is only one boy left. Keep going
at a fast pace, so that no one is out for very long.
