By simply changing the size of the activity ball, the total effect of the game can be altered. Instead of using a standard-sized ball, try playing with a ball with a diameter of 6 feet (approximately 2 m). Sometimes the ball bounces over the players’ heads, either as an unexpected consequence of players from opposite teams pushing the ball at the same time, or as an intentional strategy to move the ball over the opponents’ heads.
Back in the old days, we used to go to gas stations to inflate the big activity balls. The air compressors that top off automobile and bicycle tires can also inflate insanely huge activity balls. Before the ball is fully inflated, the cumbersome outer cover tends to flop around the ball and can be difficult for one person to control.
People just love to stand in front of the escaping air for a quick round of Hair Dryer, in which the air blows their hair around as in a high-fashion photo shoot. Players pose in front of the air escaping from the valve of the activity ball as if they are fashion models. Players take turns standing in front of the air escaping from the ball until the ball is deflated.
After the parachute descends, the players roll the ball on top of the parachute, and the game gets really interesting. A player must pick up one jack and throw it onto the parachute before the ball hits. Four players try to keep the first jack in the parachute while the fifth player grabs the second jack.
