Three or four strings should be stretched tightly from one end of
the room to the other, about four feet from the floor. An ordinary
brass ring hangs on each taut string. To each of these rings attach a
bright-colored balloon.
Divide the players into even groups, according to the number of
strings. Line them up at one end of their respective strings. At a
given signal, the leader of each line starts blowing the balloon on his
string down to the other end of the room. After each leader has taken
his balloon down to the other end of the room, he runs back to place
and touches off the next player in line, who runs down to the balloon
and returns it to the original place in the same fashion. The third
player in line then takes his turn, and so on. Of course no player must
touch the balloon with his hands. A balloon is given as a reward to the
player in each line who accomplishes the feat most quickly.
