Things You'll Need
Instructions
Find a suitable sturdy stick of a "Y" shape. You may wish to find a large branch that is "forked" and break the long branches off to a shorter size to make a suitable stick to grasp while aiming at your target.
Peel the bark off your forked stick and smooth the rough edges with coarse sandpaper. This ensures your "grasping" hand remains splinter and blister-free.
Tie a piece of elastic securely to both ends of the fork.
Pull hard on the tied elastic to make sure it won't break on its first use. Tug the elastic a few times to its full extent. If the ties come undone; retie them more securely this time.
Test your new catapult with a gummy bear or spitball, making sure you aim at a target.
