While many methods exist for building different sizes of catapults, build a simple catapult by attaching craft sticks together with rubber bands, and then gluing a bottle cap to one of the original sticks. This catapult is suitable for launching marshmallows or pom-poms.
- Paint the craft sticks
Use a small paintbrush or sponge to paint both sides of 10 large craft sticks. Use non-toxic craft paint that dries quickly. Allow the paint to dry completely before proceeding.
- Secure two craft sticks together
Stack two craft sticks on top of one another, and connect them at one end by wrapping a rubber band around the end. Keep wrapping the rubber band as many times as you can.
- Attach the remaining sticks together
Stack the remaining craft sticks. Secure the stack at either end with a rubber band wrapped around it until it's tight.
- Attach the two pieces together
Pry apart the end of the two-stick stack. Center the eight-stick stack between the two sticks so they are perpendicular to each other. Slide the eight-stick stack down to the end.
- Secure the stacks together
Attach the stacks together with a rubber band at the intersection point. Use a crisscross for the rubber bands to ensure stability.
- Attach the bottle cap
Attach the bottle cap to the outer end of one of the sticks of the two-stick stack with hot glue.
