How to Build a Catapult That Can Launch a Bean Bag
Block of wood 6x2x1
Clothes pin
Wood cube 1x1x1
Popsicle stick
Plastic bottle cap
Wood glue
Instructions
- 1 Lay the six-inch block on a flat surface. If your surface is not flat, you might have trouble constructing the catapult because the pieces could slide before the glue dries.
2 Glue the clothespin to the center of the block, making sure it runs along the length of the block.
3 Allow the glue to set for four hours.
4 Glue the one-inch block to the top of the open end of the clothespin so it looks like the block is resting on top of the clothespin.
5 Allow the glue to set for four hours.
6 Glue the Popsicle stick to the top of the block, with more than half of the stick hanging off the end.
7 Let the glue set for four hours. Then glue the cap (with the opening facing up) to the stick. You may place objects, like beanbags, in the cap to catapult.
