Give each person a colored balloon, being careful that there is an
even number of each color. The two people having the same color march
together. An extra person, who marches alone, is given a balloon of any
of the colors used. When the music stops, everyone must quickly change
partners, choosing a new one who carries a balloon of the same color as
his own. This gives the extra person an opportunity to get a partner,
who, however, must carry a balloon of his color. When the music again
starts, the new person left without a partner marches alone, waiting
his chance to get a partner.
