Video: The number of bad ideas on the internet far outweighs the good, and making art by tossing cans of spraypaint into the spinning blades of a running lawnmower falls into that former category. As YouTuber Uncle Rob also discovered, if you're not careful, your masterpiece might go up in flames before you even have a chance to sign it.

You have the Internet in your pocket. The ability to communicate with anyone in the world at your fingertips. A big and beautiful glass screen that's asking to be touched. Too bad all those things can combine into one giant firework bomb in your pants. We've all heard about phones exploding and seen the damage it causes, here's what it looks like up close. It's terrifying.
If you have ever lost sleep thinking about what military labs the world over are cooking up to shoot up, blow up, or otherwise maim their enemies (and sometimes innocent civilians), you may want to skip the list of the world's "spookiest" weapons collected by Pop Sci. Many of the 20 we are already familiar with, like nuclear weapons, the cornershot, Metal Storm guns, "Scream" beams, Rail Guns and the infamous Puke Flashlight. However, there are other technologies on the list that you may not be familiar with.
This is how you make a hot tub, hillbilly style. Three guys from the prairies of Illinois turned an old stock tank sitting in the open air into a jacuzzi, and heated it up using quicklime, that scary caustic stuff that burns your skin off if you're not too careful. A video of how they did it, using gas masks, tin baths and a lot of ingenuity, is after the jump.
Why the hell is a dismembered pair of legs walking around willy nilly with a shopping cart? I'll tell you why...To draw awareness to homeless people, and the cutthroat world of cart-pushing. It was designed in 1993 by a college student who thought the concept of using robots for hazardous jobs could be applied to the most dangerous job of all, being homeless. The student rigged the cart together using a bunch of bike chains and a couple car batteries. We're not sure it serves any practical purpose—might be better if there were hands to put things in the cart. One thing the artist definitely got wrong though: homeless people do not spontaneously burst into flames. At least not in New York, they don't.
Ken-ichi Horie, a 69 year old Japanese sailor, is planning a solo 4,350 mile trip from Hawaii to Japan using the most advanced wave powered boat on the planet. If successful, the trip would earn him a Guinness record while simultaneously proving the viability of wave powered propulsion. His boat, the Suntory Mermaid II, turns wave energy into thrust using two fins mounted beneath the bow. These fins move up and down with the waves and use them to generate "kicks" that propel the boat forward.
Homemade flame glove. Just saying it conjures up images of a fiery disaster. Despite the risks, some lunatic managed to build one using the most dangerous parts of items like disposable cameras and lighters. As you can see from the video above, the results may have been worth it. No doubt it would be cool to walk around acting like the Human Torch or an "Ice Devouring Sex Tornado" while shooting flames from your fingertips.
