As your looking at these pictures, heres some info about this gun. First, you'll notice I chose some unusual things. The green chamber is actually a pressure sprayer. This sprayer is a very good idea, as the top cap can be screwed on and off to fill it up, and it can withstand very high pressure.
I took one, and melted a hole in the bottem of it big enough for the PVC to fit through. I used some tar and PVC cement to hold it together. The metal bar on top is for stabilization, something to hold, and it just looks cool.
The propane is lit by a spark from a standard gas grill ignitor. The ignitor is secured w/ about 4 layers of duct tape. The strap is from the cord of a vaccume cleaner.
Propane is really the best propellent, and cheapest. On distance tests, the champer being filled for 30 seconds gave a distance of aprox. 200 yards. I estimate that the tank can hold about 3x more propane than it is getting. Further tests will be conducted on this. Propane also leaves nothing but water behind when it burns, so theres no need to clean the chamber.
I have yet to test the gun w/ hair-spray, but I will eventually get around to it and compare the results.
Anyways, stats:
| Amount of propane (seconds) | Distance (yards) |
| 10 seconds | ~50 yards |
| 20 seconds | ~100 yards |
| 30 seconds | ~200 yards! |
| 40 seconds | ~300 yards |
