We're just making something. But some potato gun accidents have been brutal. A year-old in Ontario, Canada, allegedly fired a potato gun into a crowd last year, hitting another teen and injuring his face.
A Kentucky man severely hurt his leg and arm while shooting a potato gun in late A year-old Ohio man was killed and two other men were injured in a potato gun explosion. The American Academy of Ophthalmology warned of the dangers of potato guns in after two separate cases involving year-old boys. One lost an eye after he was accidentally shot at a friend's house and another unintentionally shot himself in the eye while looking down a barrel, though his vision was later restored.
The academy noted that potato guns can shoot a potato feet and snap a 2-by DuPage County Sheriff John Zaruba issued a warning on the dangers of spud guns two years ago, explaining that once one is fired, there's no way of knowing where the ammunition might go.
Spud gun advocate Joel Suprise of Appleton, Wis. Williams, now 17, is blind in his left eye, which has been removed and replaced with one made of glass.
He's learning to tilt his head as he looks around the room so the slower-moving glass eye appears less obvious. Current from the ignition device -- often a grill starter or stun gun -- travels into the chamber, and a spark jumps from one point to the other, just like a spark plug in a car. The spark ignites the fuel, causing an explosion. Pressure builds rapidly behind the potato, which is wedged tightly in the barrel. When the pressure in the barrel overcomes the resistance from the potato, the expanding gas forces the potato down the length of the barrel and into the air.
Some enthusiasts find that the basic way of powering a spud gun is inefficient. An alternative is propane injection , which uses a standard propane tank to add a precise amount of fuel to the chamber. Sign up for our Newsletter! Mobile Newsletter banner close.

MIT :. The Courtneys make absolutely clear that this kind of cannon is extremely dangerous and potentially lethal. How about we all just agree now to cut off this produce-based arms race before it really gets going, deal? More from Smithsonian.
