PVC Catapult

This catapult was constructed using leftover pvc pipe materials.

Supplies

Hand saw

small cup

rubber bands

masking tape

duct tape

pvc scraps

Step 1: Design and Assembly

Choose the dimensions of your project based on the available material. You will want a square or triangular base and definitely a support to brace the vertices arms of the catapult. I used leftover connectors for the corners but you could use duct tape.

Step 2: Spring Load

i used rubber and looped together for the spring - loaded action. You will also attach the orange cup for holding the load.
