Random question for those of you who know chemistry

Does anyone know why chewing tinfoil hurts so much? Does it have anything to do with fillings? I'm going to ask my teacher once I get back to school, but that's not for a couple of days.

Anyone got any ideas?

I'd like to know why licking a winterfresh gum wrapper and sticking it on your forehead hurts! http://pso-world.com/images/phpbb/icons/smiles/icon_eek.gif

If you have fillings, bitting down on foil makes electrons move from the foil to your filling, and thus into the nerves of your tooth.

If you don't have fillings, it just tastes funky. http://pso-world.com/images/phpbb/icons/smiles/icon_wacko.gif
