Summary:

Pushing the limits of potato gun technology...


Project Description:

The main combustion chamber is a 20 gallon oil drum. I welded spark plugs into the bottom as well as connectors for oxygen gas and map gas (methyl acetylene). After loading the spud, filling it with fuel, I ignited it from 10-20 feet away with a switch wired to the spark plugs.

Other Interesting Things About This Project:

It was too powerful for spuds. They would disintegrate. So I had to make wooden dowels to fire out of the beast.
