Salter Science

Salter Science was a brand of science kits sold by Thomas Salter Ltd., a Scotland-based company which manufactured toys and science activity kits for children.[1] Kits included activities with electricity, microscopy, magnetism and crystal gardens, but the company is probably best known for their chemistry sets. The company also produced other items such as an "Adventure Kit" consisting of a water bottle, compass, toy binoculars and a real working camera. Some toys were related to TV series, such as the 'KOJAK' ACTION SET. It also produced Crafts Plaster Moulding Set's Frog & Owl.[2]
