Trying To Build a Toy PVC Gun - Progress so far
Quick update... I've spent the past couple of days trying to develop a Toy PVC shotgun that shoots rice...
It's inspired by the match gun featured in the U.S. Army TM 31-210 Improvised Munition Handbook
This is the second one I built. (the end cap on the first one was cemented on and was burnt beyond repair after multiple tests.)
I had been using the slow-motion mode on my sisters phone to analyze the shots. The video below shows my most successful test, taken on monday. (and for some reason the slowmotion mode adds really annoying music).
Unfortunately, is seems that when firing a teaspoon of rice,15 matchheads only gives a range of 2-3 meters. It would take an entire box of matches (45) to give the gun a halfway decent range. That seems slightly unreasonable to my friends.
So now I'm trying to make homemade gunpowder. I tried extracting Potassium Nitrate from some backyard soil using the method described in the handbook, but the yield was low. I'll have to come up with another process
