How to Make a Mini Dart Gun W/Multiple Fire Modes
Intro: How to Make a Mini Dart Gun W/Multiple Fire Modes
I've been playing with the idea of what cool things I might be able to do with soda bottle preforms for a little while now and this is what I've come up with. The dart gun in this video uses two different firing methods that are commonly used in larger potato cannons, a pneumatic firing option, as well as a simple combustion option. A coaxial piston valve is my personal favorite mechanism for these sort of projects, and this video shows how it works quite well through the clear chamber. For the combustion design the fuel of choice is isopropyl alcohol, preferably 70% or greater.

how many lighters do you go through in a week? because you use a lot of peso electric igniters.

I made two versions of this project (awesome, btw):
1. With a 10 oz water bottle. works great
2. With a 2 L pop bottle. Held more air, so it shot farther.
Thanks for another cool project!

what if you were to use the hydrogen gas you explained how to make in a previous video as a fuel source? I've always had that thought and have made a few alcohol fueled mini dart guns but have yet to try hydrogen gas so what do you think nighthawk would it work? Future video? It would be pretty fun to try

Alcohol is really the best fuel. Nothing else will work nearly as well.

About 60-80psi. The preforms can stand many hundreds of psi before rupturing but the soda bottle caps are the weak spot and can only stand about 100 after they've had a hole drilled through for the valve.
