we were making batteries in science and we had to answer this queshdin on our blog so here i go.
HOW DOES ZINC COPPER BLOTTER PAPER AND ELECTROLYTE SOLUTION MAKE A BATTERY?
well now thet one is a toughie....hmmmmmm..... well, i guess it makes a battery by having a chemical reaction. the blotter paper is neccesary because if you didnt have it.... you would get a short circuit. no idea what that means, though.
but whatever. so the main point is, the chemical reaction reacts and that makes the zinc loses negatives and the copper gains them. with positives its the other way around. THAT makes electricity.
