ELEFANT TOOTHPASTE MAKEN Elephant Toothpaste Science Fair Project | Make A Toothpaste For Elephants Elephants don t need to brush their teeth. You might be thinking why we need an elephant toothpaste. Picture a huge foaming paste coming out of a bottle, just like you squeeze out toothpaste from a tube. Doesn t that count as an elephant toothpaste? In this elephant toothpaste science fair project, we will learn how to amaze our friends and teachers with a few simple ingredients
Needs flesje Hydrogen peroxide (3% concentration) few dropsliquid detergent / Liquid soap Dry yeast Warm water Plastic bottle with a narrow mouth (1/2L) (Funnel) Small cup Large tray (big enough so that the paste won t spill over) Food coloring (optional) Safety goggles (this is a must as hydrogen peroxide can be irritating for your eyes)
PROCEDURE 1. Stand the plastic bottle in the tray. Place the funnel over the mouth of the bottle. 2. Pour half a cup of hydrogen peroxide into the bottle through the funnel. 3. Add a few drops of the liquid soap as well into the bottle. 4.If we want our toothpaste to be colorful, we can add a few drops of food coloring too. This is optional. If we don t add, we will get a plain white Colgate-like toothpaste. 5.Mix dry yeast and warm water in the small cup. Stir well. 6.Pour this mixture into the bottle through the funnel, and stand aside. 7. Watch the paste frothing and pouring out of the bottle. Just like someone has squeezed a giant toothpaste tube, right? Safety tip: Make sure to wear your safety glasses and lab aprons. Do not touch the paste. Though we call it toothpaste, it is not safe to touch the paste. Chemicals used can damage your clothing or skin
