Here's a way you can turn a mousetrap into a powerful handgun that shoots up to 40 feet! It launches projectiles with both power, and precision. Cheap, easy and affordable! Cost about $1.00

Some quick links to a few of the materials I used:

[✓] Tomcat brand mousetraps: amzn.to/2cHd8XF
[✓] 1-1/2” wood screws: amzn.to/2clO3zD
[✓] Drill bit: amzn.to/2cuDCtd

Project History & More Info:

I used the Tomcat brand of mousetraps because of the little yellow bait pad that came with them. I've since found the Victor brand carries a similar pad that would probably work as well.

All you really need to convert these into a mini handheld catapult are some simple tools, 2 screws, and a small piece of wood to use as a handle.

Projectiles like Airsoft BBs shoot forward over 40 feet, with speed, and relative accuracy.

I printed off a simple target, and glued it to a cardboard frame to use for practice. Amazingly, the gun fires very consistently with regard to speed and direction.
