Together, Katapultos means “shield piercer.”Ĭatapult physics is basically the use of stored energy to hurl a projectile (the payload), without the use of an explosive. “Catapult” comes from two Greek words, “Kata” which means downward and “pultos” which is a small shield.
Catapults have been used since ancient times all the way to World War I. They proved themselves very effective as siege weapons and invaluable on the battlefield. Catapults were first invented to hurl projectiles farther than any human could. The science behind a catapultĮven though your kids will see catapults as a fun activity, there is a lot of science involved with the laws of motion. Push down on the spoon and release to launch an object from catapult. Wrap a rubber band around all of the craft sticks to hold the catapult together. Place the stack of 5 craft sticks between the lolly stick and spoon. Separate the spoon and the popsicle stick. We prefer a wooden spoon to a plastic one for our popsicle stick catapult design as it gives without cracking making for a better “fling”. Stack 1 popsicle stick and the wooden spoon together and wrap a loom band around the very end.
