Very simple and inexpensive to build! The slingshot rocket may take a little practice to use, but the payoff is well worth it as you launch it over 50'!
- Use a 7" rubber band or 2 short rubber bands tied together instead of just 1 short rubber band.
- Attach a pencil eraser to the tip of the rocket. This will prevent the straw from breaking, and it will help it shoot farther.
