Protect your home or business from unwanted intruders with a pneumatic cannon that shoots water-filled ping pong balls capable of tearing holes through various materials. That, or shoot regular air-filled balls at your friends and family, leaving hilarious-yet-playful welts.

Built by Ron Kessinger and shown off at a recent maker meetup in Denver, the potentially deadly apparatus looks like the bastard child of a telescope and a harpoon gun.

As if it needs to be said, DON’T TRY THIS AT HOME. Unless you have access to a standard wall socket and a compressed air line, plus all the parts needed to build one of these. In that case, have fun this weekend.

Oh man, I would really like to once again be able to play some ping pong on a regular basis. My kingdom for a larger apartment, money for a ping pong table, and at least one friend in real life! On a somewhat related note, this weird-ass ping pong paddle is intriguing. You wear the entire thing on your hand, which I’d assume makes it an almost spiritual extension of your body.

The paddle apparently “improves accuracy, control and swing… you will notice a more intuitive, natural hit motion and superior backhand.” It’s also good for people with arthritis, “because there is no clenching.” Except, of course, when you’re gnashing your teeth together to deliver a game-point overhead smash, lodging the ball into your grandson’s forehead.

So how much would you pay for a pair of these paddles? If you said $100, then you’re in luck because that’s exactly how much they cost. If that sounds a bit expensive, then maybe you need to get more serious about the game. Or perhaps you could consider the nice extras – a carrying case, two wristbands (schweeeet!), and four ping pong balls – as something of an added value.

Vernon Graner of the Austin Robot Group has built a three-story-tall robot in the hopes of “evoking dialogue” and “finding ways to get people excited about technology again.” Mission accomplished, sir. Your gigantic robot is truly a wonder to behold.

Originally unveiled at Maker Faire back in 2007, the robot started as a device to hold a projection screen – of course, right? – but “it kind of got out of hand,” according to Graner.

The Achilles heel of table tennis: people without friends can’t play. Unless you raise the one side of the table, I suppose. But why do that when you can buy an automatic ball-shooting machine?

The Robo-Pong comes in a few different varieties starting at $229 for a basic unit (the 540) or $359 “for intermediate and tournament players” (the 1040) Finally, there’s the Robo-Pong 2040 for $695 (seen in the above video), which recycles the balls you hit back to it, allowing you to play all day and all night. There are also upgrade kits available, so you can start out with the 540 and work your way up as you improve.

The Olympics have started. Beginning next Tuesday, we’ll witness some of the most finely-tuned athletes in the world battling it out on a little green table. Here’s to Olympic Table Tennis, one of the greatest sports of all time.

Now let’s take a look at the members of the US Table Tennis Team that will be competing in Beijing, shall we?

Wang Chen returns to her birthplace, Beijing, to show everyone what’s what. She’s the two-time defending North American champ and lives in New York City.

Born: January 17, 1974 in Beijing, China

Residence: New York, New York

Height/Weight: 5’10” / 140 pounds

Event: Women’s Singles, Women’s Team

Crystal Huang lives in Southern California but often travels to her homeland to train. She says, “China has a lot more good players. The level is totally higher than here.” Ouch.

Born: July 18th, 1979 in Changsha, Hunan, China

Residence: San Gabriel, CA

Height/Weight: 5’3” / 110 pounds

Event: Women’s Singles, Women’s Team

China’s Gao Jun won a sliver medal in 1992 in women’s doubles. She came to the US in 1994. I’m beginning to think that we’re getting most of our players from China.

Born: January 25, 1969 in Dalian, China

Residence: Gaithersburg, MD

Height/Weight: 5’7” / 140 pounds

Event: Women’s Singles, Women’s Team

At 44 years old, David Zhuang doesn’t look a day past 38. I’ll give you three chances to guess where he’s originally form. Here’s a hint: He’s originally from China.

Born: September 1, 1963 in Guangdong, China

Residence: West Windsor, NJ

Height/Weight: 5’11” / 165 pounds

Event: Men’s Singles

So there you have it — your US Olympic Table Tennis Team. Good luck, you four. We’re pulling for you. And finally, here’s an awesome table tennis point…

Just one man’s opinion, but I’ve never had any beef with traditional ping pong. If you, however, find yourself longing to play on, say, a round table with five other people (perhaps all wearing mesh jerseys), then this modular ping pong table is for you.

So what about the “modular” part of the modular ping pong table? Well, it can be reconfigured to suit your fancy. Check out the mind-bending configuration below!

In fact, you can put together multiple tables, allowing “1-12 or more players to play table tennis with exciting new game configurations.” Apparently, even conventional ping pong tables can be retrofitted to accommodate your new paddle-happy lifestyle.

The “Table Tennis Triples and Modular Table Tennis System” is currently up for a 2008 Next Big Thing Award. The system was designed by Guenter Arndt and apparently there’s a book in the works with various game configurations and rules (see the website here). There’s a video of some three on three action, found here.

Ahoy, fellow apartment dwellers. If you’re like me, your apartment, even if roomy, could use more space. I mean, when you’re paying out the rear for a 2 bedroom, where are you going to put your ping pong table? You could just play Wii tennis, but seriously, real ping pong is the way to go.

If you’ve got a doorway, you can now have ping pong. This table — net and all — doubles as a door. It swings open like any standard door, but then rotates forward and back, making a playing surface. It’s sort of a sporty take on the Murphy bed.

And there’s no reason it has to be confined to table tennis. Indeed, in the future, we see air hockey doors, salad bar doors, baby-changing-station doors, operating table doors, even doors that resurrect Axl Rose’s career. Ok, that last one was a joke.
