Have you seen those youtube videos where they give step by step instructions on how to do ridiculous things like charge an ipod with a onion(fixed)? For example, note the first video here:
http://www.teamliquid.net/forum/viewmessage.php?topic_id=69462
I'm providing you with instructions that sound somewhat unrealistic, but actually work. Try it if you don't believe me.
You have a radio, such as the one pictured above, a magnet, and a coil of wire. You want to listen to your favorite station, but the other people on the bus aren't particularly enamored with NSYNC and Hanson. If you had headphones this would be a piece of cake. It turns out, there's another way to listen in.
1) Plug the coil of wire into the phones jack of the radio (the radio probably needs to be pretty powerful with the volume turned up all the way)
2) Place the small magnet between your teeth and gently clamp down (front teeth work fine)
3) Bring the coil of wire close to the magnet so that the magnet is nearly passing through the opening in the coil
4) If another person wants to listen in, they can press their ear up against yours.

id choose not listening to NSYNC over the possibility of frying me and/or the radio.
|
id rather not listen at all than look ridiculous with this thing :S.....
pretty interesting though
|
I don't understand why methods like this exist, who the hell wants to go to all this trouble just to listen to their radio.
Putting that aside it is pretty cool.. :O
|
That sounds fking amazing

The charging an iPod with an onion thing was done by HouseholdHacker--a proven hoax. If this is from the same guy/group, then it's also obviously fake. I mean for god's sake, he said you could make a high-def speaker with two paper plates, a penny, and a wire. So I'm calling bs.
On another note, I think HouseholdHacker isn't exactly trying to fool people evilly, just trying to be entertaining. At least that's the way he comes across.

Well speakers are basically wires and magnets

If you plug the wire into a speakeroutput turn the volume way up it will nock out your teeth.

LOL i just had to comment on this..Me and my friend kinda came up with a conclusion that Macgyver owned Chuck Norris in real life...

another way
less painful, works out of water too, but quality drops (its better than the teeth though)

Yeah dude, seriously, I'm not one to support protection of the dumb, but this is not actually common knowledge to anyone who has not studied electrotechnics in school. You're basically going to build a magnetic amplifier between your teeth, it probably won't harm but you'll certainly feel the jolt.

Er it's not dangerous (also note this Xcetron)

Okay here's the context: I was at a conference today focusing on physics demonstrations and this was one of the main events. Sorry to any of you who didn't believe it since it's true!
He started by explaining how to connect the coil to the radio, and then showed how he had two magnets sandwiched around the outside of a plastic cylinder. He then brought the coil near the magnets and you could clearly hear the radio coming out of the cylinder. Then he moved the magnet to his teeth and held the microphone next to his ear, and we could hear it! Sorta like how Beethoven listened to music after becoming deaf, I believe.
For those of you who thought/implied this was a serious recommendation for a solution to some problem, all I can say is + Show Spoiler +Ye wear naiveté like a cloak (bonus points to anyone who recalls where that's from)
No, you will not hurt yourself doing this. I tried it and it worked fine.

I seriously wanna do this on a bus just to see people staring at me >_>

At the 3GSM convention in Barcelona 2007, one of the companies from Japan had a bluetooth device that you could attach to any bone in your body (through the skin ofc, just press against the bone), and you would hear the music in your head. It sent vibrations through the bones to your ear, even if you pressed it against your forehead, temple, wrist, etc. I've seen that work, but it did it through vibrations, not electric current. You're saying that the amplifier won't hurt the body, okay, fair enough (though I'm still not testing that) but how are your teeth going to pick up electricity and turn it into sound? Don't you need a membrane for that?

The electric pulses in the circuit create magnetic fields which cause the magnets to vibrate. The vibrations of the magnets make your bones vibrate just like in the bluetooth device you referred to.

that would be cool if somehow they made an advanced one of these with like a toothcap.. loll
