You need:
A lemon
6 copper clips
6 sink nails
Lead wire
Steel wool
1. Rub the lemon between your hands to soften it.
2. Push the copper clips into the lemon about 1 cm apart.
3. Do the same thing with the sink nails. Make sure the two aren’t touching.
4. Take your wire and connect it diagonally from the first copper clip to the second nail. Go on to the next copper clip and connect it to the third nail – and so on. This will create a reaction between the metals.
5. Now connect a wire to each extremity – the sink nail will be the minus and the copper clip is the plus. The lemon is now ready to produce about 5 volts of electricity!
6. The next step is to take the steel wool and place some dry tinder on it, such as toilet paper. Then grab the wires from the lemon and place them on the steel wool. This creates a short circuit which makes the steel wood catch fire.
