Sixty years ago this month, the December 1961 issue of the British publication Radio Constructor gave some ideas for devices to liven up a Christmas party or, for that matter, any party. According to the author, the self-explanatory design here was an “oldie,” but was largely forgotten. To play the game, one needed to move the ring from one side to the other without touching the metal rod. According to the magazine, this feat required a remarkably steady hand, and was no doubt good for many hours of fun as the guests made an attempt.
The magazine noted that if the party was one for charity, then the guests could be charged a fee to play, earning a refund if they were able to successfully move the ring from one side to the other without sounding the bell.
Perhaps if Junior is looking for a science fair project, this one could be used as a basis for determining which of their classmates had the steadiest hand.
