This is a video of some f***ing idiot pouring liquid nitrogen into a plastic bottle, then sealing the lid and waiting to see what happens. SURPRISE: it explodes in his hand! But only after nothing happens for long enough while it’s sitting on the ground and he decides to go pick it back up again. *lifts eyepatch to reveal bouncy ball* Obviously he never played with fireworks growing up. Hit the jump for the I hope they take that damaged floor tile out of your tuition.

Picture related…enough. A 50-year old Croatian man has been arrested after seeking medical help to remove a live 11-cm anti-aircraft shell from his butt after getting it stuck up there during a sex game. The deadliest sex game. You…have been hanging out with a bad crowd. After the doctors removed the 11cm long shell, it was handed over to a member of the police anti-explosives unit, the paper said. A Zagreb police spokesman confirmed the incident but would not give any details as the authorities are still investigating. If other illegal weapons are found in the man’s home, he could face criminal charges. Oh they’re gonna find some more illegal weapons alright. If you think for one second a guy who plays anti-aircraft butt bomber or whatever doesn’t sleep with the ring-pin of a live grenade around his wiener, you’re crazy as he is (but only half the sexual deviant). Croat man risks charges after explosive sex game [straitstimes] Thanks to Daniel and Samuel L., who wonder if he started with buckshot and musket balls and worked his way up or if he just went straight for the gusto.

Granted it can only hover at 3-feet, but that’s a lot higher than your UFO. “I don’t have a UFO.” You ignorance pains me, you know that? But Shu Mansheng here? He’s smart . So smart he built an 18-foot UFO (NOT roflcopter ) out of $3,000 in parts (including eight motorcycle engines). It’s Shu’s third prototype and can hover 3-feet off the ground for a solid 10-seconds. Not sure how you can use that to fake an alien invasion , but who knows, maybe he’s gonna hang it in a tree or something. Chinese man builds flying wheel with eight motorcycle motors [dvice] Thanks to Martin, who claims he tried building a jetpack but ended up burning his garage to the ground. Martin? That was a meth lab and we all know it. Hey — let’s build something together on Faceybooks and Tweeter

This is a classification of bread clips because doctors contributing to the British Medical Journal want to create a “gastrointestinally safer” version by pointing out all the dangers the ones currently in use.

Geekdad has a bunch of tips for using the round power-cells from a dead laptop battery. These cells, called “18650s,” look like AA batteries, but have very different characteristics. Your laptop battery will contain lots of these (I have a mongo long-lived Thinkpad battery that I use while travelling with nine cells), and if any one of them dies, the whole laptop battery is rendered useless. 18650s are incredibly powerful and volatile, so be careful, because it’s easy to blow ‘em up or start a fire. That said, they’re awful handy-dandy for providing a very long charge for very bright LED flashlights, or for powering your RC vehicles. By the way, a good quality LED flashlight is incredibly bright. I tried to take some pictures and video to demonstrate just how bright, but you really have to see this with your own eyes, in person to appreciate it. And the LED is incredibly power-efficient, so it runs for a very, very long time on a single charge. Its easy to see that the future of household lighting is not compact fluorescents, but LEDs… In the video, Im actually powering the Arduino as well as the motors, and Im surprised it works. Motors tend to create a lot of electrical noise, and Ive read about many other people who ran into trouble using a common power source for their Arduino and their motors. I presume Id start seeing trouble if I was driving a heavier load than those little Lego motors. 18650 Things To Do With An Old Laptop Battery ( via Red Ferret )

Remember Mr. Slingshot ? He is like, soooooo into slingshots . I heard he likes them so much he wants to marry them . I know, it’s that serious . Me? I’m married to the lord . Or is that nuns? I dunno, but one of them used to let us drink the Ocean Spray cran-grape juice out of the refrigerator at church before it was transubstantiationed. It was a habit. HIYO — nun joke! This is Mr. Slingshot about to send a little car to meet its maker (Ford? I have no idea). Per the man himself: So I just came back sunburned and really tired, but happy because it was just a blast — so much fun. Unbelievable. I think this is the most amazing weapon — rubber-based weapon that I’ve ever made. [I'm] really proud. Well thanks for watching! And byebye. You gotta love a burly-ass dude who signs off his Youtube videos with a sweet “thanks for watching — byebye”, amirite? I am. Great, so now you’re in love with him too. I knew I shouldn’t have pointed that out! Hit the jump for the would consider bringing to a knife-fight.

Who wants a body massage? Do you own a ShoulderFlex robotic neck massager ? Awesome, then keep using it BECAUSE IT WILL KILL YOU. The Food and Drug Administration issued an alert Friday saying one death and one near-strangulation have been reported, AP reports. The latter incident occurred after a necklace and piece of clothing became caught in a rotating component of the therapeutic massager. “The FDA is concerned that the ShoulderFlex Massager presents serious health risks,” the warning stated, reports AP. The agency urges people who own the device to “dispose of the device components separately so that the massager cannot be reassembled and used.” AHAHAHAHHAHAHA @ “dispose of the device components separately so that the massager cannot be reassembled and used.” Because people WILL go through your trash and they WILL reassemble a broken neck massager. Remember folks: at least three different trash bags. Massage By ShoulderFlex Massager Could Be Fatal, FDA Warns [thirdage] Thanks to Olivia, the White Queen, who has a diamond massager because she’s fancy and a queen.

This picture: why does it exist? A 26-year old with surgically enhanced breasts discovered one had ruptured after being shot in the teat during a round of paintball . And that, my friends, is why I’m afraid to get mine done. The 26-year-old had been taking part in a game at an outdoor centre near Croydon on Saturday (20 August). She went to her doctor’s surgery on Monday, where it was discovered one of her implants had been torn apart. “We respectfully ask that any ladies with surgical breast implants notify our team at the time of booking,” says a statement on UK Paintball’s website. “You will be given special information on the dangers of paintballing with enhanced boobs and asked to sign a disclaimer. “You will also be issued with extra padding to protect your implants while paintballing.” AHAHAHHAHHAHAH! “…given special information on the dangers of paintballing with enhanced boobs…” Way to stay professional guys. “Jesus, they run a paintball center — what did you expect?” Touch. Paintball shot ruptures woman’s silicone breast implant [bbcnews] Thanks to Spikey DaPikey, who paintballs with like six pairs of tighty whities on to prevent the same thing from happening to his balls. Smart, but I’d go with at least eight just to be on the safe side.

This is an old SEGA Out-Run arcade game that’s been mounted to a golf cart and programmed with custom software that, using two hood-mounted webcams , turns real-world roads and obstacles into in-game roads and obstacles. Better buckle up! Jk jk, it’s a golf cart — what’s the worst that could happen? SPOILER: gruesome death. Yeah, better buckle up. The old fiberglass and wood cabinet was hacked up and the motors, wheels, and drive train from an electric golf cart were stuffed inside. The original steering wheel and pedals were used for the controls. Although the top speed of the in-game car is about 180 mph, that was brought down to a reasonable 13 miles per hour. The build doesn’t run on the original 68k processor. Instead, custom software is used to take real-world image data from two webcams on top of the cabinet. These images are then converted into Outrun sprites and displayed on the monitor. The software proportionally changes the speed of the in-game car, but it seems the difference between the game speed and real-life speed would be a little disconcerting. Great job guys, I’ve always wanted to drag a jogger to their death. Hit the jump for a video of the Need For Waaaaaaaaaay More Speed in action.
