How to make a Paper Gun that Shoots - With Trigger by hotentertaiment
Roll two sheets of paper on a diagonal. Begin from one corner of the paper and roll towards the opposite corner. Roll the papers in a tight roll with no space left in the center of the roll.[3]
Tape the end of the corner to the roll to prevent it from unrolling.

2
Roll a piece of paper around the tight rolls. Roll the paper lengthwise around the tight roll to create a long hollow tube.
Tape the entire edge of the roll to prevent it from unrolling.
Remove the tight roll from the hollow tube.
Repeat this process to create a second hollow tube.

3
Cut the tubes into sections. Measure the hollow tubes and make a mark on one tube at 15 cm. This should be about halfway down the tube. Cut the tube at the mark.
With the remaining portion of the first tube, cut off a 7 cm section leaving another 5 cm portion of the first tube.
Cut the other tube into five additional 5 cm long pieces.

4
Glue the pieces together to create the gun’s handle. Apply a strip of hot glue to one of the 5 cm tubes and attach it to the 7 cm piece. Line up the ends of the two tubes evenly and stack them on top of each other. The 7 cm piece will extend out to the right past the end of the 5 cm piece.
Glue the remaining 5 cm pieces to the stack.
Off-set each tube slightly to the right to create an angled handle in the direction the 7 cm piece extends backward.

5
Attach the 15 cm tube to the handle. Place a line of hot glue on the top left side of the 7 cm piece from the middle of the tube to the end of the left side. Attach the 15 cm tube extending to the left of the handle.

6
Create a supporting frame. Using the tightly rolled strips you will create a supporting frame around the handle.
Cut 2 cm off of the end of one of the tight rolls.
Bend the strip in the middle in an upward angle to create a bend of about 120 degrees.
Straighten the strip by creating another bend in the opposite direction 4 cm away from the first bend. You will end up with a gentle S shape.
Insert the cut end of the bent strip into the third tube down on the handle. (The 7 cm tube is first, a 5 cm section is second, and the strip goes in the next tube down.)
Push the strip all the way through to the end of the tube.
Make a mark where the upper portion of the bend meets the end of the long 15 cm tube glued to the top of the gun, and cut the strip at this point.
Bend the tip of the strip down slightly and hot glue the strip to the bottom of the long tube.

7
Attach the remaining strip. Flatten the remaining tightly rolled strip. Press the paper roll firmly against a table to flatten the roll. The strip will wrap around the handle to provide strength to the grip.
Cut 2 cm off the end of the strip.
Make a fold 2 cm from the cut end and place the folded end under the 7 cm tube that extends off to the right.
Mark where the strip meets the bottom of the handle and fold in the direction of the bottom of the handle.
Mark where the strip meets the other side of the handle and fold up along the handle.
Bend the strip to reinforce the outline of the trigger space created by other piece inserted into the third tube of the handle.
Use hot glue to glue the strip all the way around the perimeter of the handle.
You should now see the shape of the gun with the bent strips creating the finger rest for the trigger.

8
Add the trigger mechanism. Roll a sheet of paper in a tight roll. Tape the ends of the paper so the roll does not come undone.
Fold the rolled sheet in a 90 degree bend 10 cm from the end of the strip..
Make another 90 degree bend 1 cm from the first bend to create a tight “C” shape.
Place the end of the 10 cm section on top of the 7 cm tube. Mark the bottom portion of the C curve at the middle of the 5 cm tube. Cut the tight roll at the mark.
Insert the long end into the 7 cm tube in the trigger opening.
Insert the other end of the bend into the 5 cm tube below the 7 cm tube.
When squeezed the end of the trigger mechanism should extend out the other end of the 7 cm tube.

9
Create a firing pin. The firing pin will be activated by the trigger to propel a paper bullet from the barrel of your gun. The energy for the firing pin will come from two rubber bands.
Cut out a square with sides measuring 25 cm.
Roll the square from one corner in a tight roll to the opposite corner. Tape the end of the roll so it doesn’t unwind.
Cut off 7 cm from one end of the firing pin.
Fold 5 cm of the cut end back to create a hook.
Place two rubber bands in the hook of the firing pin.
Wrap tape around the hooked piece to secure the rubber bands in place.
Cut 7 cm from the long end of the firing pin.

10
Attach the firing pin. Insert the long end of the firing pin into the back of the barrel. The rubber bands will connect to the front of the gun beneath the barrel. Loop the rubber bands to the front of the gun between the barrel and where the support strip was bent downward.
Position the hook of the firing pin to the back of the 7 cm tube extended to the back of the gun.

11
Make bullets. Roll strips of paper 3 cm wide by 15 cm long into tightly rolled pellets.
Load the bullets into the muzzle end of the gun.
Squeeze the trigger mechanism to release the firing pin.
Shoot!
