Make a Mousetrap Gun That Shoots!


00:00:07you can turn a mousetrap like this into

00:00:10a fun little handgun that will shoot

00:00:11projectiles with power and precision in

00:00:14this video we’ll be converting these

00:00:15traps into affordable little firearms

00:00:32I picked up this 2-pack of traps for

00:00:36only 98 cents these are the Tomcat brand

00:00:38and I chose them because of this yellow

00:00:40bait pad that I’ll be using later I got

00:00:42a piece of two by two and cut it to the

00:00:44height of four fingers and that’s going

00:00:45to be my handle to modify these traps

00:00:47we’ll get them out of the packaging and

00:00:49start by removing the bait pad from this

00:00:51heavy-duty support staple and setting it

00:00:53to the side using some needlenose pliers

00:00:55we can remove the staple from the base

00:00:57and grab a marker we’re going to need to

00:00:59place some dots over the cat’s

00:01:00heel bone the elbow and one where the

00:01:02ear meets the eye a drill in an eighth

00:01:04inch bit will help turn those dots into

00:01:06holes that should end up looking like

00:01:08this I’ve got two screws from a door

00:01:10hinge that will work well for fastening

00:01:12the trap onto the top of the wood handle

00:01:13the back overhangs about quarter-inch

00:01:15and when the screws are set the trap is

00:01:17secure now the locking pin will need to

00:01:19be shortened so holding it over the

00:01:21spring and looking down from the top a

00:01:23mark is made so that it lines up just

00:01:25past the remaining hole the snips and my

00:01:27pliers will cut that to size and I’m

00:01:29double-checking that the length is good

00:01:30by holding it next to the hole it’s

00:01:32pretty much flush with the edge so I’ll

00:01:34finish it off by bending the tip back

00:01:35just a touch so it angles up at about 45

00:01:38degrees the other trap still has a

00:01:39locking pin that can be easily removed

00:01:41and used to help form the trigger for

00:01:43the pistol this hole is just large

00:01:45enough to allow the trigger to pivot

00:01:46freely on the top side I’ll cut the pin

00:01:49flush with the spring and then bend it

00:01:51over forming a hook shape this will

00:01:52prevent it from slipping back through

00:01:54the hole there’s only one thing left to

00:01:56do and that’s to add this launching pad

00:01:57so with the hooks facing up it gets

00:01:59clipped onto the trap hammer and slid

00:02:01all the way to the right side then we

00:02:03simply lift the hammer up and tuck the

00:02:04pad inward so it lays down flat on the

00:02:06platform this mousetrap handgun is

00:02:09finished and ready for testing setting

00:02:11the firing mechanism works about the

00:02:12same as setting the trap only this time

00:02:14we push the trigger up from the bottoms

00:02:16the hook slides over the locking pin

00:02:18catching it in place it’s a three-step

00:02:20process to pull the hammer back set the

00:02:22pin and secure it with the trigger hook

00:02:24by squeezing the trigger gently you can

00:02:26watch the catch slide off the pin

00:02:28causing the gun to fire

00:02:30it’s time to add some ammo and these

00:02:32airsoft BB’s hold perfectly in the

00:02:34center groove a quick test proves a fire

00:02:36straight ahead so I’ve made a little

00:02:37target for practice these things are

00:02:39pretty fast and I’m a little surprised

00:02:41the pellets aren’t penetrating the paper

00:02:43even when shot at close range to address

00:02:46that problem I’m putting pellets on

00:02:47every hole to attempt a shotgun approach

00:02:49that’s a lot more dramatic and the

00:02:52spread is about 70 degrees so it’s

00:02:54obviously more effective closer up with

00:02:56a bit of practice it’s pretty easy to

00:02:57set but if you’re feeling lazy you could

00:03:00just hold the hammer back with your

00:03:01thumb and release when you feel like it

00:03:02this also opens up an option for a

00:03:05rapid-fire approach make sure you stay

00:03:08well back when firing because there’s a

00:03:10real danger of losing an eye when the

00:03:12locking pin snaps back and hits you all

00:03:14right for a little variety I placed a

00:03:16penny on the launch pad and it’s a

00:03:18powerful shot back at my makeshift

00:03:20target range I’m interested to see if

00:03:22the penny does any better than the

00:03:23airsoft BB’s and that’s a definite yes

00:03:26the gun shoots straight ahead by moving

00:03:28the ammo forward on the pad because the

00:03:30targets are lower and this is

00:03:32essentially a handheld mini catapult

00:03:34it’s obvious that the coins get the job

00:03:36done and are surprisingly consistent by

00:03:38sliding the penny further back the

00:03:40launch angle is shifted upward and

00:03:41targets higher up can be hit even when

00:03:43the gun is held level I experimented

00:03:45with other sources of ammunition like

00:03:47this metal washer a glass pebble a

00:03:50bracelet bead bottle cap and found that

00:03:54pretty much anything small and dense

00:03:56like a little stone gave satisfying

00:03:57results I made some more guns and

00:03:59painted this one black because I like

00:04:01how that contrasted against the yellow

00:04:03launch pad well now you know how to make

00:04:05a powerful handheld mousetrap gun or

00:04:07maybe two if you’re feeling ambitious

00:04:08that’s it for this project if you
