Things You'll Need:
- 2-liter plastic soda or water bottle
- Razor knife
- Balloon
- Scissors
- Electrical tape
- Dried or frozen peas, pebbles or airsoft pellets
-
Step 1
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.
-
Step 2
Cut the stem end off a balloon using a pair of scissors and discard the stem.
-
Step 3
Place the balloon over the narrow end of the bottle top. Use tape to secure the balloon to the bottle.
-
Step 4
Drop a dried pea into the balloon. Small pebbles, frozen peas or airsoft pellets also work.
-
Step 5
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.
