Fulcrum finds his 3D-Printed Airsoft Bouncing Betty mine to be cool... "I've been meaning to make an airsoft Bouncing Betty that can be printed for a while. And I finally finished it recently. The Boomslang is a bounding airsoft land mine that uses 8 shot caps to generate a loud bang after jumping to waist height.

Bounding mines have the advantage of being able to jump out of foliage or from behind cover once triggered. And they're also cool which is enough on it's own.

The Boomslang is designed to be as easy to make and use as possible, being as compact as possible and rapid to deploy. It uses a spring to launch the "main charge" so there's no concern about gas leaking or cooling down in the winter. And like the Sidewinder this mine all fits together in storage for safe keeping."
