| You need 2 lemons ... |
 |
| A copper coin and a nail coated in zinc |
 |
| A volt meter to check how many volts the lemon battery is creating |
 |
| We combine battery cells to create higher voltages |
 |
| Then four lemon batteries create a voltage of 3.70 volts so we light up a small LED OF 2 VOLTS !!!! |
