Step 1: Materials

You will need...


  1. 1/2 or 3/4 inch pvc pipe
  2. mouse trap
  3. wire
  4. 2 by 4 piece of wood about 2 feet long
  5. nails
  6. screws
  7. caps for cap gun (which you can buy at the dollar store)
  8. some strapping to hold the pvc to the 2 by 4
  9. 6mm bb's


  1. table saw
  2. drill
  3. pliers
  4. hammer
  5. screwdrivers

Step 2: Making the Main Body

When I made the gun I started out with a piece of two by four and cut a piece of it off with the table saw to make a higher and lower part.

Next I took the pvc pipe and some of the strapping and screwed it to the higher section of the two by four.

Step 3: Making the Firing Mechanisim

To start off you take the mouse trap and you take the piece of wire holding the trap in a position ready to fire and cut it off right pass the spring of the trap. Then drill a hole right where the wire we just cut ended. then take some wire and make a hook and put it down through the hole that was drilled and make sure it can move but don't make it to loose. After that take the other end of the wire and bend it with the pliers so that it can not come out of the hole again. Now when you wind up the trap and put the piece of wire that holds it down underneath the hook that you made you can make it fire by pulling the trigger. Now you have to put some tape around the trap part that moves to hold the bb's, and also you can put a piece of wood that your had fits nicely around and make it a handle.

For a more detailed instruction on making the firing mechanism search mouse trap gun in search bar.

Step 4: Finding the Spot to Put the Bb's

I also made this little pistol version and it pretty much does the same thing except it does not have a barrel and does not look as cool. So anyways you just have to find a spot on the tape where it fires the bb strait and that's what makes it shoot strait.

Step 5: Making It Have a Loud Gun Shot

if you want the gun to be loud when you fire it all you have to do is put a nail right at the end where the trap lands on and leave a little part of it sticking out, then you take a single cap (which you can buy at the dollar store) and place it on the nail. Then when you pull the trigger you also will hear a loud bang as well as the bb being shot.
