I was applying some bathroom sealant to my daughter's bath the other day. The small of ammonia was an immediate blast from the past. It took me straight back to my chemistry set when I was a kid!
I remember it so well, a wooden rack of glass test tubes, litmus paper, tweezers, glass flasks and how can I ever forget the bottles of chemicals like iron filings and the green [or blue?] copper sulphate!
I think my set was by Merit here in the UK and it will have been around 1970 maybe. It all come in a huge flat box. Happy days and great reactions! ha ha!
Did you have a chemistry set readers?
