the starting box to the front of the target is 25 feet
It is up to the team of students to decide how
they are going to secure their device.
However, the base of the catapult must remain in
the 12”x12” starting box
If using rubber bands to power your catapult, A

Extra rubber bands may be on hand incase the ones

The overall height of the catapult can be no
