What was Lonnie Johnson researching when he accidentally conceived the Super Soaker?
Answer
A heat pump refrigeration system
The invention was not a planned endeavor for a toy but rather an unintended outcome of scientific research regarding a sophisticated new plumbing system. Specifically, the experiments involved creating a heat pump refrigeration system based on water evaporation. During this work, a forceful stream of water generated during a test provided the conceptual breakthrough for a powerful, pressurized water gun, shifting the focus from climate control engineering to consumer toy manufacturing.
