There are numerous games oriented to fuel team building such as "drop the ball," and "airplane caper." Both games intend to stimulate genuine encouragement and fun.
"Drop the ball" is a simple game that only requires a golf ball, straws and tape. The goal for each team is to make a container out of 12 straws and 18 inches of masking tape that catch the golf ball from 10 feet high. The group that gets a ball to fall into its container and stay in the container wins.
"Airplane caper" is a game where groups of two build a paper airplane and then pass it back and forth to one another without letting it fall to the ground. At the outset of each round, every team takes a step away from its partner to make it more challenging.
