First of all its important to understand what each of the 3 prongs on the plug do, the large one at the top is the earth pin which is used to ground electricity should anything go wrong, it sends electricity back away from you instead of through you and through your heart. The other two pins are live and neutral these two are the ones that must connect to the contacts in a socket to cause an electrical circuit.

You may have noticed that the ground pin is slightly longer than the other two pins, this is for a very important reason. If you look at a socket in your house and look where the live and neutral pins would have to be inserted you might notice something, there are plastic shutters covering the metal contacts that you won’t be able to open, no matter how hard you try. In order to open these shutters you must first insert the earth pin, this causes the shutters to open and the live and neutral pins to make contact with the metal inside to complete the circuit. This makes it extremely difficult for a child with a fork to electrocute themselves by accident as they have to simultaneously open the shutter and insert the fork at the same time.
