I taught the ‘Geiger Counter’ card trick to a couple of nine-year-old magic students recently. The theme of the trick is that due to ‘human radiation’ left behind on a chosen card, the Joker – your makeshift Geiger counter – can locate their card. Both of the boys loved this trick and both knew intuitively that the theme was a flight of fancy (which, nonetheless had a ring of truth to it on some level: humans do emit a form of radiation; the best fictions contain a seed of truth).
Imagine going into your local McDonald’s. A bow-tied maître d’ with a paper hat leads you to a white-clothed table where you sit down and are given menus written in Italian on parchment paper. You order (as best you can) burgers, which come served in Chinese rice bowls. You order some wine; you are told to go to a service counter to order it where it is served in a polystyrene cup with a straw. You finish your meal with strawberry ice cream served in a cheap plastic tub. During the meal they are playing loud Mexican music, and the staff are wearing 50s style American outfits while sporting curly fake moustaches and tattoos, and talking with upperclass British accents. To say the least one would find this experience disconcerting!
