The Essential Magic Conference has now uploaded all of the videos from all of the sessions, and you can watch them for just $75. It’s a bargain, go for it! OK, to the puzzle…..
Yesterday I saw a drinks machine that had three selections – Tea, Coffee or Random (Tea or Coffee). However, the machine was wired up wrongly so that each button does not give what it claims. If each drink costs 50p, what is the minimum that you have to put into the machine to work out which button gives which selection?
As ever, please do NOT post your answers, but do say whether you have solved it and how long it took.
See you Monday!
