In 1898 at an exhibition at Madison Square Garden Nikola Tesla once tricked an entire crowd into believing that they could control a toy boat by giving verbal commands - he had in fact invented Radio Control and was piloting the boat himself.
When Tesla saw the reaction of the crowd he decided to trick them into believing that they could control the boat by shouting commands and also encouraged the crowd to ask questions of the boat. In response to the question “What is the cube root of 64?” lights on the boat flashed four times. While the crowd thought that Tesla was controlling the boat with his mind he was sending signals to the mechanism using a small box with control levers on the side.
