Light Bulb
When a magician performs his tricks, I am the type of person who will sit there and rattle off a number of ways he could have possibly executed it because of course, as an adult I know it is just that: a trick and there is no such thing as magic. Or at least I thought so until I saw this Houdini-esque, wirelessly-powered levitating light bulb by Jeff Lieberman. Verifiably not an illusion, the bulb floats evenly in midair and will remain lit for years without anyone touching it, charging it or having to replace the batteries. Compared to an incandescent bulb, it uses less than half the power. Pretty unbelievable, right? But before you get Criss Angel on the phone, here is how it works: The bulb and the case contain hidden circuitry — so sneaky — that uses electromagnetic feedback to levitate the bulb a certain number of inches away from the object nearest to it. It also uses coupled resonant wireless power transfer to beam power from the housing into the bulb itself. If you're like me and this just sounds far too complex to comprehend, you can read up more on it at b e a . s t or you can just chalk it up to the much more fun explanation: it's magic!
