Catapults 

Make your very own catapult!

We DID!

Materials you will need (for a catapult made from 1 x 2 boards):

Five 1x2x4 inch boards

Two 1x2x8 inch boards

One wooden/plastic spoon 9 1/2" long

8-10 rubber bands

Four 3" wood screws

Twelve 1 3/4" wood screws

Two 1/4 x 1 1/2" long dowels

On the 8" boards, 3 1/2" from the end, pre-drill a 1/2" hole on 2" side of the board.  Just ahead of this hole, 2" from the front, drill two holes for your screws, going through the narrow parts.  Next attach the uprights to the long boards just ahead of the 1'2" hole.  Then, pre-drill the other three 1"x2"x4" boards on the ends and screw them into place.  Next, put the rubber bands through the holes on the side, and "pin" them in place with the dowels on the outside.  Place the spoon in the middle of the rubber bands and rotate the dowel tops towards the front of the catapult until tension is at the desired rate.  Fire In The Hole!

The Finished Product SHOULD look like this:
