Turn a pencil into an emergency light

Turn a pencil into an emergency light

You are stuck in the middle of nowhere and can't see a thing. Luckily you have pencil and your car battery. You can create 20 minutes of bright light using the graphite from a regular pencil, wired to the positive and negative of your car battery. Basically, the graphite serves as a bright filament for your emergency light. Follow along with this how-to video tutorial to learn the step by step process of turning a pencil into an emergency light.

in this guys case, his mind is his worst bad. all that trouble for a few minutes of light when he's got a car full of 12volt light bulbs. I guess there are different ideas of what the word "genius" truly means.

simple resistor setup, but i like the application. however, be careful with the car battery - pretty good shock potential!

yes, it must be bio-chemistry... because a pencil, wire and a battery are biological. Or, are they?!?! Whoa, my whole world is caving in around me.

I agree with most...if you can see the battery, you can see the problem...unless you have a flat tire..then I can see how this could work. Also, I bet it'd be good for getting a fire started without matches. :)

Instead of going through all the rigmorol of getting some wire, attaching it to the car battery, finding a pencil, biting the rubber off one end, attaching the wire to either end of the pencil blah blah blah...why not just sit in the passenger seat of your car, wind it back, laydown, crack one out and wait for the sun to rise - much better idea than potentially blowing your arms off, imagine what your mum would say - "How did it happen officer?" "well we think he was attempting some new sexual practice; similar to exphixiwanking, using a pencil and a car battery, basically your son was sick and now he's dead!" "Oh no, don't you think it was possible he was trying to make a light using the pencil and the battery?" "Don't be so bloody stupid!! who would ever think of that!!"

it might be dangerous if you inhale the smoke..
i saw it smoking when lighting it up..

OK everyone... I have an even better idea! You have a huge 12v battery, some wire and an entire automobile at your disposal. What makes more sense? Using a pencil you found in the glove box and tearing it in half to salvage the graphite to hook it to the wires and get 20 minutes of toxic smoke with a bit of light... or, to pull out one of your tail-lite bulbs, hook it up and use it for 3 days straight without taking your life in your hands?
