In case of an emergency, you can make your own toothpaste. This Instagram account has all the juicy details in the video below.
According to the video, start by mixing 10g of yeast with 30mL of water, then in a second cup, do a combination of food coloring with 100mL of 3% Hydrogen Peroxide. Then, pour the yeast solution quickly into the cup containing Hydrogen Peroxide.
This video was made by the educative site MEL Science. The site offers simple homemade experiments to enlighten its viewers.
The explanation behind the massive foam formation is due to the fact that yeast secretes catalase in the presence of Hydrogen peroxide. This catalase which is an enzyme accelerates the breakdown of Hydrogen peroxide into water and oxygen. The oxygen liberated then brings about the massive foam formation.
So here’s your toothpaste recipe, you can try it when the need arises.
