Avoid swallowing the toothpaste
Warning! Only under adults supervision.
Reagents and equipment:
* 50 g of baking soda;
* 20 ml of glycerin;
* 15 ml 3% hydrogen peroxide solution;
* 15 ml of water;
* 1 drop of mint flavoring;
* mixing bowl;
* container for the toothpaste.
Stir the baking soda, glycerin, hydrogen peroxide, water and flavoring until a thick paste forms. Pour the mixture into the container and keep in a cool dark place.
Particles of baking soda act as an abrasive and remove plaque, and the glycerin makes the mixture paste-like. Hydrogen peroxide kills bacteria and eliminates bad breath. The mint flavoring gives the paste a pleasant taste.
