The players stand in a large circle. One player leaves the room.
One of the players in the circle is chosen to be the generator.
Three or four other players around the circle are chosen to be electrical goods (toaster, radio etc).
All the players hold hands and the player returns from outside and stands in the middle.
The generator starts passing the current round the circuit by squeezing the hand of the player on their right.
When the current passes through one of the electrical items they make the noise of that item.
The current goes round the circuit until it reaches the generator who then passes it back the other way.
The player in the middle must guess who the generator is.
If the player in the middle picks the correct player who is the generator they then swap or after a set time if not that observant
