LAST week we asked readers to help Steve Walkley find out what his mystery items might be.
Stew Edwards and Leanne Combes wrote to say definitely that the item was a “bucket and cylinder”.
They said that it would be used by physicists to prove the Archimedean principal of buoyancy (the apparent loss in weight of a floating or submerged body is equal to the weight of the fluid it displaces).
Stewart Ross and Suzanne Glover suggested that the item was spring scales with the item to be weighed hung on the hook. Similarly Janette Siejka and Les Delaney thought the device was used to weigh items such as fish or game. Astrid Donnelly Skene and Richard Pepper suggested wall clock weights.
