900mph Ping Pong Ball!

[MacGyver]

So, I guess the fine folks up at Purdue have gotten tired of competing to see who can get their grill ready to cook the fastest. Determined not to let their boredom get the better of them, they've designed a device that can serve a ping pong ball at Mach 1.2 with roughly the same energy as a .32ACP round.

Goes to show that there really isn't anything more dangerous than a bored engineer.

its funny the new design resembles a red neck potato cannon (no insult intended I are one).

pretty amazing for it to go through a paddle!

[TNcitizen22]

I'm really curious as to exactly what it would be like to get hit by one of those...  

 

I realize its probably not a good idea, but I just have to know.

I have a new project... Anyone else in for the next shoot?

[Guest sL1k]

air compressor + refrigerant vacuum pump = pure fun

Don't they already have golf ball launchers that affix to the front of an AR-15? I suppose a ping pong ball would fit too.

[peejman]

Good ole compressible flow.  Amazing what you can do with a little math & physics. 

 

Edit... I'm surprised they published the dimensions of the nozzle.  That takes all the fun out of it.

Pretty cool, but what a waste of time. Says the guy sipping coffee, sitting in front of his iPad, surfing the web. Edited February 5, 2013 by BigK

This coming from the guy who was taping primers to the end of darts and launching them out of a blowgun.

Yep, I have one. They also make a beer/Coke/Pepsi/whatever can launcher. Come to one of the shoots and you can fire mine.

Thanks for the invite, but I don't make it out east too often. When I was a private we used blanks in our M16s to make cleaning rod launchers to see who could stick one into a tree.

Nope.  An excellent way to get the kids engaged in applying classroom theory to something real.  Wish I'd gotten to build something this cool in school.

Had to throw the offer out there.

 

The infamous squirrel killing cleaning rod?

Did you notice anything you post lately is a double post double post?

Haha, I'm pretty sure harming any animal in the woods surrounding Ft. Benning comes with a $10,000 fine of some sort. Every thing we did in the field came with a safety brief 10 minutes long about the various wildlife you can't touch for fear of immediate execution. If you even fart in the presence of a red cockaded woodpecker I'm pretty sure that's 20 years in Leavenworth.

I did, and do notice that. Dunno why it happens.

 

Also what time were you thinking about stopping by? I probably won't be in until 2:30 to 2:45.
