The Pritt Stick
This was invented in 1967 by Dr Wolfgang Dierichs, a researcher at Henkel. Whilst on a business trip by plane, Dierichs observed a woman applying lipstick and during the course of the flight mulled over the possibility of the same mechanism being used to apply glue. He was immediately struck by how clean it would be – no pots or brushes. As luck would have it Dierichs worked in Henkel’s adhesives division and the rest as they say is history.
