Experiment: Elephant ToothpasteElephant Toothpaste anyone? Although elephants might not be too excited about the idea, you may be thrilled with the fun chemical reaction of this super simple science experiment.With only a few common items that you probably already have at home, you can see the quick and impressive results of the chemical reaction, feel the heat released from the process, and even play with the “elephant toothpaste” foam afterward.Below you’ll find detailed instructions, a materials list, and an easy to understand explanation of why it works!Elephant Toothpaste Science ExperimentSupplies Needed2 Tablespoons Warm Water1 Teaspoon YeastFood ColouringHydrogen Peroxide – Either 3% or 6%Dish SoapEmpty Plastic BottleFunnelHelpful Tip:?You can find the 3% at most stores, but you will need to either go to a Beauty Supply Store or order the 6% online. In the video I perform the experiment using the 3% peroxide.Elephant Toothpaste Experiment DetailsStep 1 –?Combine two tablespoons of warm water with one teaspoon of yeast and mix until the yeast is completely dissolved in the water.Step 2 –?Pour 1/2 cup hydrogen peroxide into the empty bottle.Step 3 –?Add a few drops of food colouring into the bottle.Step 4 –?Add a squirt of dish soap into the bottle.Step 5 –?Pour the mixture of water and yeast into the bottle.Step 6 –?Sit back and watch what happens.Helpful Tip: You may need to gently swirl the bottle in order to get the items to completely combine. How Does the Experiment Work?This experiment shows a very impressive and fast chemical reaction! Hydrogen peroxide is a combination of hydrogen and oxygen (H2O2). In this experiment, yeast is a?catalyst?that helps release oxygen molecules from the hydrogen peroxide solution. A?catalyst?is a material that increases the rate of a reaction, so the release of oxygen molecules in this experiment happens FAST! The foam created in this chemical reaction is made up of very tiny oxygen bubbles. These bubbles result when hydrogen peroxide (H2O2) is broken down by the yeast into water (H2O) and oxygen (O2).During the reaction, feel the bottle. It will feel warm to the touch because it is an?exothermic reaction. An?exothermic reaction?is a chemical reaction that releases energy through light or heat (in this case, heat).The reaction will continue and foam will be produced until all of the hydrogen peroxide (H2O2) has been broken down into water (H2O) and oxygen (O2). ................
