Preparation materials: standard copy paper, rubber band, adhesive tape and scissors. Make a gun handle. Place the copy paper horizontally with the long side facing yourself. Then fold it in half from bottom to top, and finally wrap it into a 4cm wide strip. Secure both ends of the adhesive tape and the upturned edge with adhesive tape. Fold it in half again to form a crease in the middle.
Repeat the above steps, and then make two strips with a width of about 2.5cm and 1.3cm, fix them with adhesive tape, and fold them in half, as before.
Take out the 4 cm wide paper for making the gun handle. Fold down one end of the paper strip at a position about 2.5 cm away from the central crease so that its upper edge just passes through the end of the crease. Repeat this step at the other end.
How to make a paper gun that fires bullets? Step 4, cut a hole along the crease in the middle of the gun handle, just a little more than 1.3cm, which is the socket of the trigger. It may be easier to cut by folding it in half along the crease. Be careful when cutting. Don't cut it too big.
Fold the paper that made the gun handle in half along the crease in the original direction. So the two ends of the paper money are completely stacked together. This is the backbone of the paper gun, and the barrel and trigger should be mounted on it.
Install the cylinder. Insert a piece of paper with a width of 2.5cm into the newly folded gun handle, and the two ends of the paper pass through the cuffs on both sides of the gun handle respectively. This looks like a gun. Check whether both ends of the barrel are installed on the handle.
Cut a small gap at the end of the barrel and put the trigger here.
Load the gun. Tie rubber bands at both ends of the barrel. The rubber band should be put on the notch at the end of the barrel to cover the end of the trigger.
