At-Home Science Experiments: Elephant's Toothpaste

The bubbles that your child produces in this experiment are similar to toothpaste squeezed out of a tube - just do not let them get into your mouth!

1/2 cup 20 volumes of hydrogen peroxide water (20 volumes are 6% solutions, which can be obtained from hairdressers and hairdressers)

Note: As you can see, foam will spill out of the bottle, so be sure to place it in a clean place or place the bottle on the tray.

Hydrogen peroxide may irritate the skin and eyes, so wear goggles. Adults need to pour hydrogen peroxide carefully into the bottle

Add about 1 cup of liquid detergent soap to the bottle and shake the bottle to mix

Now the adventure has begun! Pour the yeast water mixture into the bottle (the funnel will help) and observe the start of the foam!

Bubble is the best! Bubbles are special as all small bubbles are filled with oxygen. Yeast acts as a catalyst (aid) for removing oxygen from hydrogen peroxide. Because of its very fast speed, a lot of bubbles are generated. Would you ask your child whether the bottle is getting warmer? The experiment causes a reaction called an exothermic reaction. That means that it not only generates bubbles but also generates heat! The bubbles produced are just water, soap and oxygen, so you can clean it with a sponge and pour any excess liquid into the bottle.

In this test you can also use a hair care version of hydrogen peroxide or a weak version pharmacy, but the pharmacy version is not very effective. Readers should use goggles for any experiment, and adults should be able to read instructions on containers for safety.

Make elephant toothpaste is an easy and enjoyable scientific experiment that you can do with your child or laboratory students at your home. As a result of chemical reaction, a large amount of bleeding will be generated. Foam movement looks like a toothpaste released from a tube and the amount of foam is usually enough for an elephant to brush its teeth. Pour the yeast mixture through the 3 funnel into the bottle. Quickly retract the funnel and remove it. You can pour your child into yeast, but if they are young, keep them in their arms so that the bottles will not overflow. To ensure stability, use a short bandwidth base. Please confirm that the neck is thin to enhance the effect

What is the elephant's toothpaste related to science? And since each bubble is filled with oxygen molecules, the bubbles you want to make are unique. Yeast acts as an adjuvant (catalyst) for removing oxygen from hydrogen peroxide. This happens very quickly and makes a lot of bubbles. You may notice that the bottle feels warm. It is because your experiment involves an exothermic reaction which is an exothermic reaction. As bubbles will spill out of the bottle, be sure to experiment with a cleanable surface or tray.

Elephant toothpaste is a foam substance caused by the rapid decomposition of hydrogen peroxide by using potassium iodide as a catalyst. The rate at which the reaction proceeds will depend on the concentration of hydrogen peroxide. This is a popular experiment done by children at school and parties because it requires only a small amount of ingredients and becomes "bubble volcano"; this experiment is also known as "marshmallow experiment" but psychological Stanford It has nothing to do with the marshmallow experiment.

, (HO ·) and (HOO ·), decomposition can follow different paths to form free radicals. The non-metallic catalyst contains potassium iodide, which reacts particularly quickly and forms the basis of an elephant toothpaste experiment. Hydrogen peroxide can also be biologically degraded by enzyme catalase. The decomposition of hydrogen peroxide releases oxygen and heat; this can be dangerous as it can cause immediate fire if high concentrations of hydrogen peroxide over flammable materials overflow.
