2. Super-Strong Craft Stick Catapults

Every boy needs a catapult. This classic DIY uses potential energy to launch pom-poms or marshmallows across the room. It’s simple to build but provides endless entertainment for target practice.

  • Materials Needed:
    • 10 jumbo craft sticks
    • 3–5 sturdy rubber bands
    • 1 plastic bottle cap
    • Glue (hot glue works best)
    • Projectiles (marshmallows or pom-poms)
  • Steps:
    • Stack 8 sticks and rubber band them tightly at both ends.
    • Take the remaining 2 sticks and rubber band them together at just one end.
    • Slide the big stack in between the 2 sticks, as far back as it will go.
    • Use another rubber band to secure the whole thing in a “cross” shape.
    • Glue the bottle cap to the end of the top stick to hold your ammo.

Pro Tip: Move the 8-stick stack closer to the front or back to see how it changes the distance and height of your launch.
