Cutting the Metal

Use a regular pocket knife and cut the metal. Start in one part and then rotate it around. Save it because you'll need it later.
Balloons


Find two balloons and cut them pretty low. Lower than in the picture.
Shooting Mechanism


Put the cap in the two balloons and put it in one side of the tube. Then fasten with tape and a rubber band. After done, take out cap through top.
Add Handle

Cut a handle, and connect with tape.
Duct Tape

Cover with duct tape, it should look pretty cool at this point.
Finishing Touches


Add a jar sealer on the top and any other cool looking stuff you want. Make it your own.
