Things You'll Need
Instructions
Use a razor knife to cut the neck from a soda bottle or water bottle. Discard the bottom part of the bottle. Cut 2 inches past the bottom of the neck to leave enough to hold onto. Sand the cut edge lightly.
Cut the stem end off a balloon using a pair of scissors and discard the stem.
Place the balloon over the narrow end of the bottle top. Use tape to secure the balloon to the bottle.
Drop a dried pea into the balloon. Small pebbles, frozen peas or airsoft pellets also work.
Grip the object inside the balloon and pull back. Aim at your target and release. Pulling farther back on the balloon increases the shooting force of the pea.
