OK tell me I am not imagining this. In the 1950's I remember being taken to a shoe shop as a child, to be fitted for shoes. In the shoe shop there was an X-RAY MACHINE and you stood there, with your feet inside this machine. You were asked to wriggle your toes and the assistant could look through a viewer at the top - sort of like a ship's radar- and see whether the shoes fitted you properly. Can any one else remember such a thing? ..In my mind I seem to associate them with "Clark's" or "Start-rite" shoes for some reason. Were they actually X-ray machines in the true sense of the word, with a radioactive source, etc?

I realize this is 1st sem chem stuff, but that was 20yrs in the rear view mirror, and I have to explain how to adjust the pH in the pool to my wife. I want to put a simple spreadsheet together for her so she knows how much acid to add to reduce the pH in an 8700 gallon pool. TIA
