In week 5 Oliver and Kate showed us Makey makey which is an electronic board with wires that you can use to control games. The person that is holding the earth/green cable is the one that can control the game. With all the other wires you can plug them in to anything and when you tap the object it does something to the game. For example you can plug a cable into a banana if you are holding the earth/green cable you can tap the banana and it will count as a key on a keyboard and it will make something happen.
