Bifocal safety goggles


Dewalt's bifocal safety goggles come in strengths from 1.0 to 3.0 and at $10/pair, you can't go wrong, especially if you, like me, are losing your vision as you hurdle towards senescence -- better Mother's Day present than flowers, better Father's Day present than a tie. (Thanks, Ian!)

Annabel de Vetten was trained as sculpture and painter, but after making her own wedding cake, she found a new passion in life: confection. Annabel's creations aren't ordinary at all, as seen previously, and she works creating molds from the things she loves. Skulls. Animals. Horror films. Whatever takes her fancy. 3fa77925fd0acb796248815be25877f1_original

But making awesome chocolate creations isn't easy. To make truly amazing and consistent chocolate, a professional tempering machine is necessary. Help make the world of chocolate a better and more beautiful place by supporting Annabel's Death in Chocolate Kickstarter. f7544abbe30dd2c5e13023cc73bcb198_original d735612fa7e19163d8179a6669571251_original 1398392_orig

Hoax photos of real events


Jojakim Cortis and Adrian Sonderegger normally produce beautiful commercial photos, but their hobby is recreating iconic photos -- the Hindenberg's explosion, Nessie 1934, Tiananmen 1989, 9/11, and more -- in miniature, so that their replicas are virtually indistinguishable from the originals.

Book Preview: The Boy Who Played with Fusion

boy

This June, Harcourt releases The Boy Who Played with Fusion: Extreme Science, Extreme Parenting, and How to Make a Star. Written by journalist Tom Clynes, the book got its start as a 2012 Popular Science story of the same name. I've been reading an early galley and love the way Clynes weaves tales of a precocious youngster, his wise parents, and his baffled teachers. It’s an inside look at raising a typical, angsty teen, except one who gives Ted talks on the weekends and hangs with world-class physicists.

Taylor hadn’t realized that his biggest challenge, by far, would be to create a workable vacuum. He needed enough negative pressure to create an almost empty space for his subatomic particles to travel. If any gas or air molecules were left inside the tube, the high-energy particles would collide with them and lose energy. “Imagine a freeway in Los Angeles and you want to go 100 miles an hour,” Taylor explains. “If you try that at rush hour you’re going to hit other cars. But in the middle of the night it’s wide open and you can go fast.”

To pump out the tube, Taylor used a refrigerator compressor and wired it to run backward. Then, Taylor loaded the deuterium gas he’d generated. “I was so excited,” he says. “Me and Tom got the Van de Graaff up to 200,000 volts, and with the Model-T arc we tried to get plasma going.”

But even though they used higher-tech fasteners than Lawrence did in the 1930s, they had trouble creating enough vacuum to get a sustained plasma field, and a clear enough path to accelerate particles to any measurable degree. They tweaked the fasteners and tried all sorts of sealant—silicon rubber, epoxy, “and a few other things,” says Taylor. “We were using techniques from the sixties and seventies, and we modernized them, but with our expertise and materials we could only go so far. Most of it worked. But not the big picture.”

How to make a technicolor igloo

Firefighter Jostein Alvestad built this igloo in his backyard by filling 32 plastic buckets with colored water each night. In a Chicago magazine story, he describes the fun of sleeping and hanging out inside by candlelight. The exterior issues a soft glow when a flashlight is brought inside.

Igloos are usually built with snow that has sintered, or compacted, in the wind. A good guide to more traditional structures is How to Build an Igloo: And Other Snow Shelters.
