Catapult Instructions(School)

This is the cataplt me and my team came up with to conserve recources

When i say 2 feet i mean 1 so keep that in mind when cutting the wood

Take 2 2x4x6 and attach them to 2x4x2 at the corners using nuts and bolts

Secure the other 2x4x2 the same way on the opposite side as shown in drawings Secure a 2x4x5 vertically 1.4 inches away from the edge (refer to image). Drill a hole 2-3 inches above the base of the catapult and copy on the other side.take 47 ft of rope and fold it by 3 ft like a paper fan.run the rope through the hole and secure the rope using the knot in the diagram at the to of the page.
