News: 4 Years of Spectacularly Pointless Marble Machines

So very pointless, yet unquestionably spectacular. The best kind of "art" performs no other function than to delight the viewer, and Japanese YouTube user Denha's complex marble machines do just that. But are marble machines art? You can call them that—or toys, scientific contraptions, engineering feats—but however you choose to label them, the best marble machines are complicated, skillfully crafted, and driven by the principles of potential energy, kinetic energy and gravity.

News: Weston Price Foundation

The Weston Price Foundation is the gold standard for truly good nutrition. Weston Price was a dentist practicing in the 1930s who over the course of many summers visited fourteen different native groups and correlated the health of their teeth to what they were eating. He consistently found that as long as the people ate their traditional whole foods diet, their teeth (and the rest of their bodies) were healthy. When they started eating Westernized foods their dental and overall health deteri...

News: Rainwater + Solar Power = DIY Rainbow Machine

Artist Michael Jones McKean has harnessed nature with his DIY rainbow machine, a mechanism that uses reclaimed rainwater and solar power to shoot man-made rainbows across the sky at whim. High powered jets and fountain nozzles shoot a heavy wall of rainwater into the air, creating a faux rainstorm. Sunshine does the rest.

News: Gassho and Kokoro

At the beginning of every class, or almost every class, we do a series of exercises. The Japanese word for this sort of calisthenic exercise isundo. These exercises derive from the Goju style of karate created by Miyagi Sensei in Okinawa in the early part of the 20th Century. In devising these exercises Miyagi no doubt borrowed liberally from the Chinese, whose influence on the southernmost island of the Japanese archipelago was immense.

Freedom watch: Not a single Democrat voted for ending raids on raw milk

Here’s some news for those who still somehow believe the political left in Washington cares about the People. After U.S. Senator Rand Paul introduced an amendment that would have ended armed FDA raids on raw milk farmers (http://www.naturalnews.com/035966_Rand_Paul_FDA_censorship.html) and legalized free speech about the curative properties of medicinal herbs, nutritional supplements and superfoods, are you curious how many Democrats voted in favor of this?

How To: Decode Body Language

Your boss is pursing her lips and drumming her fingers on the table during your presentation. Your best friend is gazing downwards and crossing his arms when you ask him why the car you lent him for the weekend has a big dent. What could these body language signals all mean?

How To: Make a Self-Watering Greenhouse

I've been hell-bent on complete self sufficiency for a long time now. There was a point where I was living in a self-sustaining community in the mountains in Colorado, and we had a very large greenhouse there. Dragging the hose around to water plants was a real pain, and that stuck in the back of my mind even after I left the place. It would have been much easier to integrate watering into the frame at construction time than doing that hose dance every day.

Receipt Racer: A Paper and Laser Tangible Video Game

Video games have been a purely digital medium for some decades now. They exist in the electronic nether, embedded on discs and projected on screens. Since digital distribution has gained popularity, even the physical manifestation of the game disc is going away, leaving games (especially digitally distributed indie games) more ethereal than ever before. It is unclear whether this slightly unsettling fact was on the minds of the three people who made Receipt Racer, but regardless, it stands as...

News: Möbius Pasta + Jell-O Jigglin' at 6200 FPS

Food is the meeting place of left and right brainers: Culinary arts call for creativity, but is also deeply rooted in the What, Why and How of basic science—baking powder vs. baking soda, the rising of dough, the falling of a cake, etc. Below, two plays on left brain principles—the Möbius strip and the law of gravity—both executed with right brain flair.

News: Zoetrope + Bicycle Wheel = Cyclotrope

Kudos to student Tim Wheatley, who came up with this incredibly nifty DIY animation using a bicycle wheel, cardboard cut-outs, and wire to create a magical reinvention of the classic zoetrope, Earth's earliest form of animation (it first surfaced in China around 180 AD!). Simply give it a spin, and the animation comes to life. Inspired to make your own? First, learn the basic principles of the zoetrope here or here. Next, take a little advice from Tim to add the "cyclo" element:

News: Building a Bonafide Solar Death Ray Sounds Too Easy

Eric Jacqmain is one smart cookie. Borrowing from the same principles of Archimedes’ mythological death ray, the Indiana teenager used an ordinary fiberglass satellite dish and about 5,800 3/8" mirror tiles to create a solar weapon with the intensity of 5000x normal daylight. The powerful weapon can "melt steel, vaporize aluminum, boil concrete, turn dirt into lava, and obliterate any organic material in an instant."

News: Creepy Theremin Utensils Howl the Pain of Slaughtered Ghost Chickens

One of the creepiest musical instruments ever is undoubtedly the theremin, a device originating from the early 20s that emits eerie sounds with a just a wave of the hand. If you've seen the original movie The Day the Earth Stood Still, you know what I mean—freakishly creepy. Playing the theremin can be off-putting for some, since it's a relatively pricy gizmo, but a new geek gadget called the EaTheremin aims to make all of us professional, dinnertime theremists.

How To: A/C Broke? Keep Your Car Cool with This DIY Solar-Powered Air Conditioner

This air conditioner works by using sunlight to heat air at the bottom of the unit. The hot air rises, allowing the ...
