Making a catapult out of wooden craft sticks also known as "lolly sticks" is a project that can keep a child occupied. He will be delighted when he discovers the catapult actually works to fling small objects across the room. This is a great project for scouts, lessons on medieval weapons, or to relieve a rainy day.

Things you need
- 32 wooden craft sticks
- Paper water cup, trimmed down to 5 cm (2 inches) high
- Rubber band
Make three triangles out of the craft sticks. Each triangle side will be made with three sticks, for a total of 27 sticks. To make each side, lay two sticks end to end and tape them together by wrapping the tape around them. Centre a third stick on top of the two and tape it to them securely. Repeat this for each of the nine sides.
Complete each triangle. Lay two side pieces end to end and tape securely. Lay the third side piece end to end with these and tape securely. Fold into a triangle and tape the two loose ends together. Repeat this process twice more until you have three triangles.
Place two triangles together and tape one side. Spread them apart and slide the third triangle between them. Tape the third triangle to each of the other two so that you have a three-sided pyramid.
Make the arm. Lay three craft sticks end to end and tape them together. Lay two more sticks centred over where the original three sticks meet and tape them on. Take the trimmed down paper cup and place it on the arm 2.5 cm (1 inch) from the top. Tape it securely. Use as much tape as necessary to ensure it will not fall off.
Place the end of the arm without the cup into the triangle, taping it securely to the furthest corner on the bottom. Place the rubber band around the arm just under the cup and loop it around the top point of the triangle, taping it in place in both spots. Place a projectile in the cup, push the cup down, and release to fire your catapult.
Tips and warnings
- You can also glue the craft sticks together (except where the arm attaches to the frame) for a sturdier catapult.
- Paint your catapult to resemble a real siege engine.
- Make sure an adult is present when firing the catapult.
- Do not aim the catapult at a person or animal.
