Instructions
1. Wash the coins thoroughly and dry them.
2. Roll the lemon across a bench, pushing down to 'juice' the lemon.
3. Ask an adult to carefully cut two small slits in the lemon rind, fairly close together.
4. Place the coins into the slits, making sure they dont touch each other.
5. What will happen if you touch your tongue to the coins at the same time? Try other foods!
6. If you have a multimeter, try measuring the current created in the circuit.
