Catapult – Preparation (en)
PREPARATION
To start making your catapult get together all the materials that came in the pack and pay a lot of attention to the small parts, so that they do not get lost:
MDF Parts (wood)
Rubber Band – it will help you understand elastic potential energy! When an object is stretched, it is storing elastic potential energy. When we stop stretching it, it goes back to its initial shape, transfering the energy to the surrounding environment, in this case, to the projectile that will be launched!
Furry balls – These are your daring projectiles! Of course we’re all for world peace so these are very cute and fluffy and won’t even hurt an ant.
Ready? Move on to making the catapult!
