Marble Gun

[mikemurph]

This is my new marble gun, it's powered by about 9 seconds of butane. It shoots metal ball bearings very fast. I made it in about 20 minutes, not including finding the junk around the house. It can leave a fair sized dent in a wall, and wrecks cans. I hope you like it, and tell me what I should do to improve.

Damage Shots (front entrance and exit wound)

Very nice. I have found that for softer targets a more impressive splat can be made by using a lighter projectile so it hits at a higher speed. Here is a empty juice can hit with a jawbreaker. A heavy projectile would have been much slower.

Nice ghetto launcher. I'm impressed with the performance. That HDPE jug is pretty tough. Edit, added zoom of the damage.

This was a pretty tough target, it was about 4x the thickness of a soda can, it was an old green gas can, It had to be tough to withstand the pressure. Thanks for the tip, I might try it and post some pics

That HDPE jug is pretty tough

Yea, it inflates a tad bit when I use a burst disk, but it holds well

Not exactly sophisticated, but it clearly works.

Why are all of those images mirrored?
