How to Make a Piezoelectric Gun

Hi, guys I'm back with another DIY project this time I'm making a gun from a piezoelectric please leave suggestions in the comment box below. Enjoy!

So what you're gonna need is bottle a plastic bottle or a metal flask I used a Nike bottle I had laying around and a piezoelectric you can find it inside a lighter the small button type thing and it can also be purchased on line or at any hardware store then what you're gonna need are two screws the have to metal of course other than that a tic tac box for the handle and the tools are a drill and a hot glue gun.

so for the handle you're just going to glue the tic tac box to the bottle and you're set to go.

The wiring is pretty basic you just have to drill to holes in the tic tac box and a slit for the piezoelectric and hot glue it all in place the drill two holes in the back of the bottle for the screws and the tighten the screws in a v shape (picture attached above) for the spark to happen or all will fail. The last picture shows the screws from inside the bottle.
Quick Tip
don't hot glue the piezoelectric from the front side or it will not work only glue it from the opposite of the Button side for it to work.

I sawed of the head from the bottle so you're left with this and insert a straw from the front for the Bb's

Then you're done just put the head on the bottle and spray alcohol inside then press the trigger that's how it's made
