Lush bath bombs are really popular because of the physio-pleasure associated with using them. They’re pretty expensive, so buying them feels like purchasing an experience. There is also stimulation from new releases and the desire to try all the different types. They also look super cool in action. (I actually almost worked for Lush and was hired to make their bath bombs in their “ballistics factory!” I learned how to make bath bombs in the interview process but I accepted another job. After seeing the process required to make them, the price seems reasonable!)
