If you are lucky enough to have an extra roomba kicking around why not mod it to shoot peoples feet. 🙂 “I own a Discovery roomba and use it in the never ending battle against dog hair. I love it as it does an amazing job at sweeping up not only dog hair but all sorts of dirt and dust. I didn’t want to take the chance of killing it
Modified Ink Printer Prints Electronic Circuits
Don’t throw away your old HP ink-jet printer, Seyed Bidoki has developed a way to print electronic circuits with it. “A desktop printer loaded with a silver salt solution and vitamin C has been used to produce electronic circuits. The UK researchers behind the feat say their experimental device could pave the way for safer and cheaper electronics manufacturing. PhD student Seyed Bidoki loaded a standard Hewlett Packard ink-jet printer
Ferrofluid Morpho Towers – Two Standing Spirals
Ferrofluid is cool stuff, Sachiko Kodama and Yasushi Miyajima have built a spiral that demonstrates the beauty of the liquid. Video after the jump. “Morpho Towers–Two Standing Spirals is an installation that consists of two ferrofluid sculptures that moves synthetically to music. The two spiral towers stand on a large plate that hold ferrofluid. When the music starts, the magnetic field around the tower is strengthened. Spikes of ferrofluid are
Sulfur Hexafluoride Experiment
Sulfur Hexafluoride is an interesting gas, it basically has the oposite effect of helium. It is heavier than air and when inhaled it makes your voice deeper. Does anyone know where to get this stuff? One more video after the jump. “Because the gas has a high density (over five times denser than air), it can be poured into open containers, like beakers and fishtanks. Moreover, light objects, e.g.
Homemade Rocket Motor Test
Who said building and testing rocket motors in your basement is dangerous? “This is the first static test with our homemade tar/oxygen hybrid rocket motor. James Turner and myself (Eric Stackpole), and two of our friends, Jeff Bernard and Caleb Lesher did this project last summer because we wanted to learn more about how rocket engines work. We built the rocket in James’ garage in Humboldt County, CA completely
The Obelisk Chairs
I love the concept of this chair set, but the price took me by surprize! What would you pay for this chair set? I am thinking that it would be worth about $500 to me… “The Obelisk Four powdered coated aluminum frame chairs w/white cushion and table stacked into one piece made out of woven polyethylene. It’s very durable on the exterior and interior, so it’s built to last.” Via:
