Sometime the projects you see at the local hacker space are better left a secret when you return home for the evening. Case in point, this ping-pong ball launcher that can put holes in a sheet of OSB. The projectile is made more lethal because the ball has been injected with water to dramatically increase the density. Compressed air is used to propel it from the 14 round magazine with devastating effect.
We’ve embedded a video of the gun being fired after the break. The creator, [Ron Kessinger], demonstrated this at a Denver hacker space called Club Workshop. We’re hoping there’s no plans for turret automation because this thing’s dangerous! Either way, the significant other who usually watches out for our safety would never approve.

This is a completely pointless hack but a completely awesome one.
That is insane…
that is a ping pong ball launcher turned up to 13 (forget 11, that was passed)
I like the guy walking up to see the damage before the gun has been powered down. 14-round magazine you say?
i can think of another ping pong ball launcher i wouldnt want the wife to know about…
this could revolutionize paint ball… and give me one more reason to build a carbon fiber Master Chief costume.
Here’s a parade that needs some rain. If I put some lead shot in a pillow, I didn’t make a lethal pillow. This is just a complicated water gun.
I dunno, if you put lead shot in a pillow, then shoot that pillow at someone with enough force, it could be lethal. Anyone want to check to see what the penetrating ability of his gun is?
By definition, if it is full of lead shot, it is no longer a pillow. It is a sack of shot.
I am pretty sure that once you fill it with water, it is no longer a ping pong ball.
you beat me to it vidiot !!!! was thinking the same thing when i read the headline
i’m glad i’m not the only one with a warped mind eric!
“this could revolutionize paint ball… and give me one more reason to build a carbon fiber Master Chief costume.”
wow thats fucking lame.
HAHAHA DISREGARD THAT, I SUCK CAWKS.
Hell – fire a pillow fast enough, no lead shot needed, and you’d have enough energy to kill something. (whether you can achieve such velocity outside of a vacuum is another matter entirely)
Calling this a “water gun” is like calling the Columbia River a “slight trickle”
you guys are belittling homosexuals here, please change ‘wife’ to ‘spouse’.This is very offensive.
If I had a husband, I doubt he would disapprove of homemade cannons.
Maybe his wife helped him build it; you don’t know.
OK, everyone whose ‘significant other’ would be fine with you bringing this home please raise your hand.
I thought so.
Hell, my wife sent me the video just before you posted it. She included the tag line:
“Would this keep the deer out of the garden better than that motion sensing sprinkler monstrosoty you built?”
(Though I’m not sure I quite follow the innuendos here, so may have missed the joke!)
Ooh, that was meant to be a raised hand but the script seems to have stripped out anything between my > and <'s :)
I don’t see why everyone is so stunned that ~30g of water moving at a few hundred FPS will go through common building materials…..
@ Mike Szczys, my wife would cheerfully help me build something like this – or more likely build a ‘rival’ one of her own to compete in destroying things.
Geek wives FTW!
Like a few others – filling a ping pong ball with water to make it lethal means it’s no longer just a ping pong ball.
If you can fire a regular ping pong ball through OSB then I’ll be interested. Shooting something with the approximate mass of a golf ball through OSB is not so impressive.
It may no longer be just a ping pong ball, but I think the point is that the gun IS “just a ping pong ball launcher”. IE, your light cannon is going to be found technically legal, unless loaded and used in a less than legal manner. Great for all those high-powered weaponry nuts. ^_^
I somehow think a vehicle mount would get you pulled over though.
Yeah, anything attatched to a car that can move off of the car is illegal. Google McMissile, where a woman was charged with firing a missile from her vehicle (said missile was a McDonalds cup).
Apparently, no one around here knows how to make a tennis ball incendiary grenade. Fire one of those babies out of that thing and you’ve got artillery!
Your thoughtfulness shows in everything you do.
