Aerosols were invented by a Norwegian named Erik Rotheim in the 1920s to help him put wax on his skis. The most expensive aerosol made was a diamond spray used to rub down precision moulds.
However, the most popular aerosols are deodorant and body spray which were first introduced in the UK in 1954. The first aerosols in the UK were insecticides, though, made in 1949.
Pepsi decided to make an aerosol for astronauts so that they can drink cola in space. Without the aerosol can, the cola would spray all over them and soak them.
Aerosols are good for many things, including
- Helping pigs mate and help lambs accept foster mothers.
- Empty aerosols can be recycled.
- In Japan, they use them for coffee and chicken soup.
- The U.S. has ketchup, cheese, and mustard aerosols.
