- Ritter Sport chocolate started to be produced in the shape of a square after jackets with square pockets became popular in the 1930s. The company decided to set up production of square chocolate bars that would fit into these pockets but would not break and had the weight of regular chocolate.
- Locust bean seeds were once considered identical to each other and used as a weight measure — a carat (equal to 200 mg). Since then, the carat has become a traditional measure of weight for precious stones and pearls.
- In 19th-century England, macassar oil, which supposedly aided alopecia, was popular among men. To protect furniture from oil stains, housewives began to cover the backs of furniture with napkins.

- At the entrance to large buildings, revolving doors are often installed, and here is the reason why: opening a hinged or sliding door even for a short period of time (especially during cold or hot weather) leads to significant temperature changes in a room.
