Contribution 5 - Toothpaste
The ancient Egyptians invented toothpaste by mixing rock salt, mint, dried iris flower, and pepper. The mixture would turn into a paste-like consistency when it came in contact with saliva. Even tho we do not use the same ingredients toothpaste is widely used all around the world today. I would show this at a museum by having an area where you can make your own Egyptian toothpaste.
