Have students line up on a starting line and have them prepare to race to the finish line. The only challenge is that each student must take a balloon and put it between their legs and place their hands over their heads. This is a funny activity to watch but warn your students to be careful not to lose their balance.
Extra Challenge: There are usually many balloons not being used during this activity so I just spread them out across the floor and tell them that these are land minds that they will be eliminated if they touch them. This makes the activity even more exciting.
