The Materials You Will Need:
Step 1: Take Out the Insides
Take the cardboard piece out and remove all confetti.

Step 3: Finish Weapon
Put the cardboard piece back in the party popper
Step 4: Fire!!!
Pull the string and let a rip!
This is my first instructable and was a smaller project than what will be put on later.
