I had seen a lot of projects where people used perfume as an explosive. After seeing many of these projects, I decided to try to build my own. I used some common household items to make it, in the end I’m happy with the results.
I used a syringe for the chamber and a few other components. For the ignition system I used a push igniter that used piezoelectric energy. For the barrel I used a plastic straw. When I had everything ready I assembled it. This projects uses Q-tips as ammo.
Before testing with ammo, I tested the ignition system. Spray perfume into the chamber and pull the trigger.
To make it fire, what you have to do is take the back part off of the syringe and squirt some perfume in. Then you close it back up and put the Q-tip in the barrel. When you press the igniter it creates a small spark that sets the alcohol in the perfume on fire. The alcohol expands when its on fire and it shoots the Q-tip out of the straw.
