While in Tennessee last week, me and my buddy made a home made potato gun .. here is the video he put together of us shooting it.. the good shots towards the end went 150+ yards.. it was pretty fun to do.
hope you enjoy, thanks for checkin it out

Damn that looks fun, I would go to prison if i shot that thing around here.

 

Now I like mashed pototoes but that seems like a funny way to make them

 

It was very fun, im making my own here...
They only cost like 30$ or so to make
You can shoot potato's 150+ yards for fun

the one at 2:55 was the best one.. it was so loud too
its amazing what some hair spray and a spark will do..

 

Pretty sweet, all that is simply hairspray and a spark? Impressive.

 

Oh yeah, lotsa different ways of making them...lol If you stand behind a wall downrange you would be amazed at the sound of a potatoe flying by! I made a few different ones including a pneumatic one back in high school. Easy way to get into trouble though, much much louder than a gun/rifle.

 

lol they are loud, i can agree to that
and yes all that from some PVC, potato, hair spray n a spark..

 

Just a little hint from when we used to make Spud Cannons back in the late 80's. Try some WD-40 for your propellant. It lubricates the barrell so you get cleaner shots. Only problem is that it fouls up the sparker a little quicker.

 

i already spray cooking oil in the barrel every time i load a potato to slick it up..
then load the back in with hair spray and let her rip!

thanks though sir

 

Haha that's awesome, me and my friend were firing off his potato gun a few days ago but we only had some Right Guard deodorant spray to use
