I want to get some trip mines to evaluate their effectiveness in games but the production ones are a little too spendy if deployed in numbers. I wanted to know what the communities opinion is on home brew mines from both a safety and practicality standpoint. Also, would a powder/noise mine work off of the 10 foot kill zone rule of grenades?
The designs I'm thinking of specifically are a spring loaded plunger in a tube topped with a retaining bar for the plunger to launch confetti or powder, and a home brew 40mm shower shell trigger.
(I hope this is the right place for this, I looked around and couldn't find anything on the subject.)
