I used to believe it was possible for me to leave a bunch of dominos on a table in a random layout, name a shape, leave the room for 60 seconds, then come back in and the dominos would have magically rearranged themselves into whatever shape I'd said.
I later realised this had worked because my grandparents had been present in the room when I first put the dominos out, and they'd heard me declare what shape I wanted. When I left the room, they of course did the rearranging.
