Elephant's toothpaste is a foamy substance caused by the rapid decomposition of hydrogen peroxide using potassium iodide or yeast and warm water as a catalyst. The foam could overflow from the bottle, so be sure to do this experiment on a washable surface, or place the bottle on a tray.
Watch the process video below of how to make elephant toothpaste with kids below!
How to make elephant toothpaste with yeast. Pour 2 inches of hydrogen peroxide (3%) into the bottle. Prepare yeast solution by adding dry yeast to warm water and wait a few minutes until it becomes frothy. Pour the hydrogen peroxide into the bottle first, adding a couple drops of food coloring if you wish, and a generous squirt of dish soap.
Have you tried making elephant toothpaste with kids? Nick uhas and david dobrik stunned the internet with their successful attempt at breaking the world record for largest amount of foam produced via the elephant toothpaste experiment.; If you want to replicate their attempt on a smaller.
Pour the yeast mixture into the bottle then quickly step back, and watch. Soap (dawn works great!)yeast (the little individual packets work great!a note about hydrogen peroxide: How to make steve spangler’s hydrogen peroxide and soapy yeast foaming reaction learn how to make steve spangler’s elephant toothpaste recipe using safe and easy materials you can find at home.
You can color the demonstration and make it into an elephant toothpaste christmas tree for the holidays. Place bottle on baking sheet. Because it requires only a small number of ingredients and makes a volcano of foam, this is a popular experiment for children to perform in.
3+ tablespoons (15 ml) of warm water; Mix together with a spoon. The soap is used to trap the oxygen as it is formed, creating the foam.
Pour the yeast into the bottle and withdraw to observe the chemical reaction that occurs. We used a funnel for the next bit to make it a little easier. The science of elephant toothpaste.
Mix thoroughly, about 30 seconds. In a measuring cup mix together one tablespoon of yeast and three tablespoons of warm water. What materials do you need to make elephant toothpaste?
A child with a great adult helper can perform this activity safely, and the results are wonderful. A small volume of hydrogen. Pour the yeast mixture in last, and watch it blast off!
Foam is produced more slowly, but you can add a fluorescent dye to this reaction to produce elephant toothpaste that will glow very brightly under a black light. In a bowl put a tablespoon of baking powder and three of warm water. Set the bottle in a sink or outdoors or some other place where you won't mind getting wet foam everywhere.
How does elephant toothpaste work? Pour 1/2 cup hydrogen peroxide solution, 1/4 cup dishwashing soap, and a few drops of food coloring into the bottle. Yeast can be used in place of iodide for a slower reaction, but this also allows you to add fluorescent dye to the mixture to make a glowing elephant toothpaste when you shine ultraviolet light on it.
Pour the yeast mixture into the bottle and watch what happens! They will go down the sides and, as the elephant toothpaste grows, they will drag it. The yeast acts as a catalyst that causes the peroxide molecule to release the oxygen atoms at a much faster rate.
The yeast is a catalyst that takes the oxygen away from the hydrogen peroxide which then gets trapped by dish soap from lots of bubbles! How rapidly the reaction proceeds will depend on the concentration of hydrogen peroxide. The next step will make a bit of a mess, so protect your surface with a plastic table covering or large pan.
Chemically, hydrogen peroxide is made of two hydrogen atoms and two oxygen atoms (h 2 o 2). The temperature doesn’t have to be exact, but the temperature you use for a hot bath is good. In this reaction, hydrogen peroxide is breaking down into water and oxygen.
If you’re not familiar, the experiment features the creation of a large, foamy volcano made from water, dish soap, yeast and hydrogen peroxide—commonly referred to as “elephant toothpaste. Swish the bottle around to mix the ingredients. A bit about the chemistry here.
The yeast acts as a catalyst to speed up the reaction. Swish the bottle around to mix. Hydrogen peroxide (see notes below);
Watch it on igtv (instagram tv) as well. You will not be able to walk into walmart or target and just pick up different percentages of hydrogen peroxide for the elephant toothpaste science experiment! Stir for about 30 seconds.
Hydrogen peroxide (3%) dish soap. We're gonna show you one of our favorite science experiments have you ever wondered how an elephant brushes his teeth with elephant toothpaste, of course now to make your very own elephant toothpaste. In a glass bowl or measuring cup (i found the measuring cup easier when it came time to pour), mix three tablespoons very warm water with one packet of dry yeast.
How to make elephant toothpaste the instructions below will work for 10, 20, and 40 volume peroxide. You're gonna need two tablespoons of warm water one teaspoon teaspoon teaspoon of of of of yeast. You can use yeast instead of potassium iodide.
Carefully and slowly pour in half a cup of hydrogen peroxide. In a small cup or bowl, mix the yeast with the warm water. Follow the activation directions on the packet of yeast, adding warm water and waiting until it begins to fizz.
In a separate small cup, pour one pouch (about two teaspoons) of dry yeast and add two tablespoons of warm water. The hydrogen peroxide typically bought at the drug store is 10 volume. You’ll see here that we have two bottles.
Add the dishwashing detergent and swirl the bottle a little to mix the ingredients so far.
