Why does a slingshot work?

Have you ever wondered why a slingshot is able to launch a small projectile with such force? It's a simple tool, yet it can propel a pebble or a marble a surprising distance. What's the science behind this? Is it the elastic nature of the rubber bands or the way we pull back on the pouch? And how does the release of the pouch convert the stored energy into kinetic energy, sending the projectile flying? Let's delve deeper into the mechanics of a slingshot and uncover the answer to the question, "Why does a slingshot work?
