The guys over at openMaterials have figured out a great recipe for a DIY magnetic ink that you can use for an interesting art project—or just to mess around.
A New Breed of Invertebrate: Half-Rat, Half-Silicone Cyborg Jellyfish
A team of scientists might have just put Jellyfish Art out of business with their new cyborg jellyfish. By arranging the heart cells of a normal rat on a piece of silicone, they've successfully created their own Franken-jellies. When in salt water with a fluctuating electrical field, the rat's heart muscles on the rubbery silicone contract the lobes downward and back up, which mimics the pulsing movement of a young moon jellyfish swimming.

William scoured through all of the comments and chose the two winners he felt best deserved a pack of Sugru.
Robot Basics: Using an H Bridge to Move Your Bot Backwards
I love robots. They have the potential to evolve into Asimovian destroyers of the human species, but have only just mastered the art of cleaning my rug. They have an ever increasing cool factor and a growing number of cheap and simple components that let the hobby roboticist reach for the burning miasmas of plasma. But to get to the stars, we need to start with the basics.
Elementary Sputnik Satellites: How to Make Trash Bag Hot Air Balloons
Sputnik was the very first man-made object to be sent into space. Though it was a truly epic accomplishment, all this Soviet sky surfer actually did was transmit a constant beeping noise back to the surface.

How To: How Hard Is It to Land on the Moon? New Space Game Gravitates Towards Space Physics
If you're like me, you were disappointed when NASA cut their human space flight program.

How To: Prank an Entire Dorm with a Perfume-Spraying Swiffer WetJet Booby Trap
Pranks are fun, but finding a way to maximize the affect of a prank can be tricky. Toilet papering the whole campus or repainting all of the parking spaces slightly smaller can take a long time and a lot of resources. A better plan of attack is to booby trap the choke points where your victims are forced to pass through. Think like a guerrilla. A dorm doorway is a good idea.

For beginners, the free Google SketchUp application is the best choice of software. Using only a few tool bar buttons and a scroll wheel computer mouse, you can model literally any obje...
Contest: Spud Gun
Well here it is, this is an older pic but it still works, the only change from this pic and the current cannon is that I have put some duct tape around the PVC bonds and am planing on spray painting it. The compression chamber is over a foot and a half long at 2" diameter PVC to push the spud or what ever you can out the cannon. The barrel is a little more than a foot long. This was originaly a prototype with all 1" PVC pipe but I cut it all off and attached a few PVC sizers and made the barr...

Post-Modern Vandalism: How to Hack Together These Everlasting Light Graffiti Throwies
Graffiti is a great way of getting your message out to the masses. The earliest known graffiti dates back to 30,000 years ago and used the traditional apply-paint-to-wall technique. Though our paint now comes in cans and not from scavenged berries, the actual graffiti process hasn't really evolved from those first cave paintings.
DIY Lab Equipment: Make an Etch Tank for Rapid PCB Fabrication
I love making my own printed circuit boards. It really gives a professional look to a finished project, and having all the design files means I can whip up another batch whenever I need to. However, when I need to make, say, three thousand swarmbots or fill an order for a dozen PCBs, the traditional etching process can slow down the operation to a crawl.
