AMAZING ELECTRONIC MAGIC!!
A ‘switch board ‘ with four colored LED on a plug that fit into matching colored sockets and four switches under them.
You demonstrate that ONLY the switch under the plug ( of the same color ) is the ONLY one that controls the LED of the SAME COLOR.
Then interchanging the LED’s ( plugs ) at random. The switch of ANY other color STILL CONTROLS ONLY the LED of the SAME color, and is the ONLY one that does so, regardless of the socket it’s plugged into!
