The catapult was invented by the ancient Greeks. It is one of the most effective mechanisms in times of war. With a little effort you can throw something really heavy at a great distance, for example at an enemy tower.
This model took virtually minutes to make. We just had to wait for the glue to dry…
You will need: a wooden base, a clothespin, a lolly stick, a bottlecap and good instant glue.
We glued on the clothespin, then the lolly stick, then the bottle cap. To be on the safe side, we tied the whole thing with twine. 🙂
