Spring Power in a Slingshot DIY

Today I’m excited to show you a truly unique DIY creation — a spring-powered slingshot, where I replaced traditional rubber bands with extension springs. This unconventional mechanical approach will be interesting not only to slingshot enthusiasts but to anyone fascinated by hands-on engineering and experimental physics.

Typically, slingshots use elastic bands or rubber tubes, which come with several downsides: they wear out over time, can snap unexpectedly, and often provide inconsistent tension. I decided to try something different — replacing the rubber with metal springs. The result surprised me: consistent pull force, greater durability, and surprisingly powerful shots.

The slingshot was made using wood, steel tension springs, and a leather pouch for the projectile. The final product is both functional and visually unique, standing out from standard designs.

In the video, I walk you through every step of the build, test the slingshot with different types of projectiles, and share my thoughts on its performance.
