To occupy my nephew for a few hours I asked him to solve a Rubik's cube that had been on the mantelpiece unsolved since 1992, my own childhood. He solved it in a minute, he's still bored, and I am now also resentful.
@fesshole you can look up how to solve them on your phone nowadays. If you can follow the walkthrough it’ll solve it from any given starting layout in 5-10 minutes.
