Each team gets a roll of duct tape and a set amount of time to complete the goal. What is the goal? No one knows until it begins. Past events have been:
1) Build the tallest free standing tower.
2) Build the strongest bridge.
3) Build the strongest sword and battle with it.
4) Build the best soap box derby car
5) Build a working catapult (you got a rubberband and a ping pong ball as well)
6) Build a the largest jack-a-lantern
7) Build a working track-mania track
8) Build a egg drop safety harness
9) Build a pendalum
10) Build an air propelled rocket with ballast
You can use the duct tape on one roll, not the plastic covering, not the cardboard inside.
