you can also use regular household hydrogen peroxide but the reaction will be smaller, 20-Volume hydrogen peroxide which is 6% (, 1 Tablespoon of dry fast acting yeast (use the little packs). Give the solution a quick swirl to mix the contents. Pour the KI/soap solution into the cylinder. Step 2 - Pour 1/2 cup hydrogen peroxide into the empty bottle. What percent of hydrogen peroxide is best for elephant toothpaste? More by the author: It is a experiment similar to Experiment #2, decomposition of Hydrogen peroxide generate Oxygen, which turns detergent into foam. Gases and liquids are made of molecules or inert atoms that are moving about relative to each other. Adding yeast to hydrogen peroxide then, rapidly increases (catalyses) the decomposition of hydrogen peroxide into water, oxygen gas and heat (you will notice that the foam produced feels warm). We have a PASSION for SLIME, and are dedicated to helping you make the best slime ever. Otherwise, you can place it inside the sink. Put the yeast in a small cup or bowl, and add about 3 tablespoons of warm water to activate it. Join us on our journey to discover just how cool science can be. Wear safety goggles. However, the reaction just makes the solution warmer, not hot enough to cause burns. There is a small chance you might get some of the foam in your eyes while doing this experiment, so its important to stay safe! STEP 1. Comparing the Original Reaction With the Kid-Friendly Recipe.

Place down a tray first to catch the eruption. Place the plastic water bottle on the baking pan or tray, and make sure you are in an area that is easy to clean up- bathroom, kitchen or outside are all good options. See notes below for Proof amounts. 1 Tbsp dish soap. How to Make Elephant Toothpaste: In a separate small cup, add 3 Tbsp. Safety Precautions 30% hydrogen peroxide solution is a strong oxidizer. Food coloring can color the film of the bubbles so you get colored foam. STEP 5. Step Six Pour the yeast mixture through the funnel into the bottle. Try 3, 6, 9, 12% hydrogen peroxide solutions all found at Sally Beauty. Add a healthy squirt of dish soap. Detergent solution captures gases to form the foam. The reaction occurs immediately upon the addition of the yeast. Procedure Place the glass cylinder in the basin. For scientific purposes of course! While the yeast is growing, take your empty bottle and start adding the other ingredients to it. A 16-ounce plastic soda or water bottle OR a bucket that size. A steaming column of suds spurts out of the top of the cylinder. Follow. Im not sure where the elephant toothpaste description came from, except that when it comes out of a bottle, it looks a bit like toothpaste (particualrly if you dye it blue), and its big and frothy, so I suppose it would be the size an elephant would need to brush its teeth. Learn the science behind the elephant toothpaste demonstration using hydrogen peroxide and a catalyst. Then, a catalyst, often around 10 ml potassium iodide solution or catalase from baker's yeast, is added to make the hydrogen peroxide decompose very quickly. How to Do the Elephant Toothpaste Explosion Experiment. It looks like it could be from a giant tube of toothpaste! Does changing the amount of each ingredient change the reaction? Usually, it takes a long time to make elephant toothpaste. The kid-friendly version uses a lower concentration of hydrogen peroxide, with the decomposition catalyzed by yeast. Food coloring. However, if you choose to use household hydrogen peroxide (3%) found in most stores, we have touched the foam safely. The kid-friendly version uses chemicals that are safe for children to touch, in case of a splash. In this experiment, 30% or 35% hydrogen peroxide is mixed with some liquid soap, and then a catalystis added, to make the peroxide rapidlybreak down. 150mL 3% Hydrogen Peroxide. Keep reading to find out how to transform this classic science demonstration into a real science lesson and STEM activity. 31,431. Steps for making elephant toothpaste: Place the water bottle in a tray to catch the overflow once the experiment is done. Hydrogen peroxide breaks down naturally over time, especially when exposed to light, but in this reaction the yeast causes that breakdown to happen much quicker. Elepahant toothpaste is actually a chemical reaction between yeast and hydrogen peroxide. If you want to make your foam a single color, add a few drops of food coloring directly into the hydrogen peroxide, and. Retrieved from https://www.thoughtco.com/kid-friendly-elephant-toothpaste-demo-604164. We will use some common household chemicals to make a big reaction. STEP 3. The recipe used is the same as the one listed below but we started with 2000 ml of hydrogen peroxide. Make it a true experiment and try three different size containers! There are several different recipes online, but most agree. Pour the yeast mixture into the hydrogen peroxide/soap mixture and watch what happens! Helmenstine, Anne Marie, Ph.D. "Kid-Friendly Elephant Toothpaste Demo." First mix 50mL of detergent with 100mL of 30% hydrogen peroxide. INSTRUCTIONS: Step 1. This fall season we are exploring some cool Halloween theme science experiments. You can also make a version with and without dish soap. Substances are made from different types of atoms, which combine with one another in various ways. Catalysts were first written about in 1794 by a Scottish chemist named Elizabeth Fulhame. Add food coloring to this if you like. Does changing the container you do the reaction in change the way the foam moves? Set the bottle in a sink or outdoors or some other place where you won't mind getting wet foam everywhere. Helmenstine, Anne Marie, Ph.D. (2021, September 7). Swish around. The first thing you're going to want to do is mix the teaspoon of yeast and a few tablespoons of warm water together in a separate small cup or a small bowl. STEP 2. Otherwise, you can place it inside. The elephant toothpaste science experiment is a good one to use as a examination of why its important to stay safe in the science lab. Mix 3 US tbsp (44 ml) of warm water with the yeast and let it sit. That is because this reaction is exothermic - it releases heat as a form of energy. However as you can see in the photo above my son had no problems handling the foam once it escaped from the container. We recommend a simple face so the foam can come out easily. Quickly pour the yeast into the bottle, while swirling the liquid vigorously to mix well. Observations and Results. This experiment was selected for Science at Home because it teaches NGSS Disciplinary Core Ideas, which have broad importance within or across multiple science or engineering disciplines. A Kid-Friendly Elephant Toothpaste Recipe. Elephant Toothpaste . There are several different recipes online, but most agree that you get the best reaction with the 12 percent hydrogen peroxide solution (called "V40 developer") you can find at beauty supply stores the kind you use to bleach hair. In a separate container, mix a packet of active yeast with a little warm water. What to do: Prepare yeast solution by adding dry yeast to warm water and wait a few minutes until it becomes frothy. Changing the ingredients can change the reaction, Its important to take safety precautions when working with chemicals. Step 1 - Combine two tablespoons of warm water with one teaspoon of yeast and mix until the yeast is completely dissolved in the water. We've updated our Privacy Policy, which will go in to effect on September 1, 2022. Add food coloring of choice, about eight drops. Place the funnel in the plastic bottle. Due to the chemical reaction of elephant toothpaste the internal temperature can soar pretty high. Just ask us! All measurements are per container. It goes like this: Hydrogen peroxide (H2O2) is a reactive molecule that readily decomposes into water (H2O) and oxygen: In this demonstration, yeast catalyzes the decomposition so it proceeds much more rapidly than normal. Atoms form molecules that range in size from two to thousands of atoms. Check it out again!. What You'll Need: A clean 16-oz plastic soda bottle. Wearing the gloves, carefully but quickly add the hydrogen peroxide solution to the cylinder. The mixture will then produce a massive foam. Put your.
