=THE CAPITAL OF CATAPULTS=

This catapult has wood on both sides with 4 wheels and 2 axels. Then there is a base of of wood to hold the catapult and a rope and handle to pull it. There will be a spoon to hold the ammo and to shoot it then a lever will be attached to the side of the wood. A spring pushing against a pulley creates potential energy.

What we need
1. 4 wheels 2. 2 axels 3. rope 4. 1 spring maybe 2 5. 1 wooden spoon 6. 6 normal wood 7. 1 pulley 8. 1 handle/wind up 9. 8 or more screws 10. 8 bolts 11. rocks (ammo) 12. handle 13. glue 14. foam 15.hook 16.2 small axels 17. gravity

How to build
Start off with putting 2 pieces of wood for the main body. Drill 4 holes across the underside of the body and nail the axels on. Attach the wheels onto the axels and screw the bolts on either side of the wheels. Then screw in the base of the sitting point of the cannon part. Glue the spring on. Attach the handle to the back of the base wood. Then attach the pulley to underneath the cupped wood. Then add another rope and the handle/windup. Then put to sides of wood with a hole at the top so you can fit in an axel. Attach the axel to the wooden spoon and slide it in to place.
