How do lolly stick catapults work
When you push down on the arm of the catapult, the lolly stick bends, giving it energy. When the arm is released, the energy is transferred to the spider, which flies through the air.
The further down the catapult arm is pushed, the more force is used, which gives the lolly stick more energy to transfer to the spider, making it travel further.
