If you bike a lot and live in a small room or apartment, it can be tough to find the space to store your wheels.

A few weeks ago, we saw a simple 128 inch DIY Projector Screen that looked like a pro built it—and it only cost $200. But this one is even cheaper, and looks just as good. It's also simpler because it's painted right onto the wall. In the video below, How To Lou shows us how to make it with just some white or silverscreen paint, a few pieces of casement molding, and some black velvet for the trim.
So, you want to throw a steampunk party and you have almost everything in place—your steampunk persona and iPhone are ready to go, and you've even got your own steampunk straight razor.

Got an upset stomach or a little heartburn? America's favorite pink pill will cure it right up. But did you know that there's actually metal hiding in those chewable Pepto-Bismol tablets? Yes, metal. Technically, it's a poor metal, but metal's metal, right? Well, we do tend to eat a lot of iron in our diets, because it carries oxygen throughout our bodies, so consuming metallic minerals isn't anything abnormal. But you'd never think that Pepto-Bismol is actually made up of metal.
Looking to transmit some super-secret audio communications to your other spy buddies? A laser is the perfect tool for getting your sounds heard from a small distance—without anyone intercepting them— even if it's just a cover of your favorite pop song. A laser audio transmitter uses light rather than radio waves to transmit sound. This is a much more secure way to send audio communications because the laser is a focused beam of light, whereas radio waves are not controlled, so they can be pic...
A spectrometer is a device that splits light into all of the different colors it's composed of that can't be seen with the naked eye. It does this by using a prism to refract or bend the light. Jeffrey Warren over at Public Labs created a tutorial showing how you can make your own video spectrometer and create spectra like the one pictured below. Any guesses as to what the subject is? Believe it or not, that's what whipped cream looks like when viewed through a spectrometer. You can do this w...
Believe it or not, it's possible to make your very own lava—if you have a furnace capable of heating up to 1,200 degrees Celsius, that is. Bob Wysocki and Jeff Karson started the Syracuse University Lava Project to study basaltic lava and give students a hands-on way (hypothetically, of course) to learn about it. Oh, and they also want to use it for art projects. Sign me up for that class! It all starts with 1.1 billion-year-old basalt gravel, which apparently anyone can buy. They put the gra...
We've all played with bubbles as kids, but I think most would agree that they're not exactly the most functional of objects. An international team of researchers made up of Yoichi Ochiai, Alexis Oyama and Keisuke Toyoshima wants to change that. They've figured out how to project both 2D and 3D images onto a micro membrane (soap bubble) using ultrasonic sound waves and a standard projector. The bubble is made of a solution of sugar, glycerin, soap, surfactant, water and milk. The glycerin and ...

For his thesis at Design Academy Eindhoven, artist/designer Tuomas Markunpoika Tolvanen created this incredible chair using tubular steel cut into thin rings. How did he get them to stay that way? He burned them. His project is called Engineering Temporality, and the inspiration came from his grandmother whose Alzheimer's disease is deteriorating her health and memories. Once he cut the rings, he laid them over an existing chair, only partially covering it. The fire acted as a varnish, creati...

How do you make a 1950 Studebaker even cooler? By installing an iPod Nano in the dashboard, of course!

Here's how they pulled it off.

And she shows you how to make one, too!
