The secret ingredient in the famous elephant toothpaste experiment is a catalyst, which supercharges the breakdown of hydrogen peroxide into water and oxygen gas.
Add 1 tablespoon of dish soap into your bottle or vessel (Fig 1). Measure ½ cup of hydrogen peroxide and pour into your vessel with the dish soap (Fig 2). Swirl to mix. Add 10 drops of food coloring (your choice of color) either into the mixture or pour along the sides of the bottle or vessel (Fig 3).
Potassium iodide is a common catalyst used in science demonstrations like "elephant toothpaste." It can generally be found through the following types of retailers:
Pour 1/2 cup hydrogen peroxide solution, 1/4 cup dishwashing soap, and a few drops of food coloring into the bottle. Swish the bottle around to mix the ingredients. Set the bottle in a sink, outdoors, or someplace you won't mind getting wet foam everywhere.
To make elephant toothpaste erupt higher, you need to speed up the chemical reaction so that more oxygen gas is produced and trapped in a shorter amount of time.
If your elephant toothpaste isn't foaming, it usually comes down to one of four common mistakes. Troubleshooting the reaction relies on these key adjustments:
A 12% hydrogen peroxide solution is not safe for direct skin contact or consumption. It is a strong, corrosive oxidizer that can cause severe skin burns and irreversible eye damage. It requires protective gear (gloves, eye protection) and must be heavily diluted before use.
Most famous "failed" experiment
Michelson and Morley's results. The upper solid line is the curve for their observations at noon, and the lower solid line is that for their evening observations.
Supplies You'll Need for the Unicorn Toothpaste
Soap acts as the foaming agent in the elephant toothpaste experiment. When the catalyst breaks down hydrogen peroxide into water and oxygen gas, the soap traps the rapidly expanding oxygen molecules. This captures the gas into thousands of tiny bubbles, transforming it into the thick, erupting foam characteristic of the reaction.
KI is also added to table salt ("iodized salt") to provide a source of dietary Iodine. The U.S. Food and Drug Administration (FDA) classifies KI as a nonprescription drug, approved for over-the-counter sale, as a safe and effective method to protect the thyroid gland from radioactive Iodine (radioiodine).
Adults over 40 years old have a much lower risk of developing thyroid cancer. They are also more likely to have health conditions, like problems with their thyroids, that increase the risk for harmful health effects from KI.
The best catalyst for elephant toothpaste depends on your safety needs and the concentration of hydrogen peroxide you use.
Hydrogen peroxide is a chemical substance that has many uses around the home. It can be used as a surface disinfectant, stain remover, and bleaching agent. An unopened container of hydrogen peroxide will last for around 3 years, but as soon as it's opened, it'll expire within 6 months.
Description. About 50 ml of concentrated (>12%) hydrogen peroxide is first mixed with liquid soap or dishwashing detergent. 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.
Rainbow elephant toothpaste is an awesome, kid-friendly STEM experiment that creates a massive eruption of colorful foam. You can make it by mixing hydrogen peroxide and dish soap, adding food coloring along the inside of your container to create stripes, and pouring in a yeast-and-water catalyst.
If your elephant toothpaste failed to foam, it usually means the chemical reaction stalled, the gas escaped without foaming, or the fuel for the reaction was missing.
The recipe called for one drachma (1/100th of an ounce) of rock salt, two drachmas of mint, one drachma of dried iris flower, and 20 grains of pepper. The scribe said that when crushed and mixed together, this made a “powder for white and perfect teeth.”
Einstein was never able to prove the unified field theory, he commented in April 1950 that "all attempts to obtain a deeper knowledge of the foundations of physics seem doomed to me unless the basic concepts are in accordance with general relativity from the beginning".
Pitch (a derivative of tar or bitumen) is the world's slowest known liquid. It is about 100 billion times more viscous than water and is so thick that it appears to be a solid—even shattering like glass when struck.
The Rainbow Milk experiment (or Magic Milk) is a quick visual science activity. You drop food coloring into milk, add a drop of dish soap, and watch the colors burst and swirl. The soap breaks the milk's surface tension and reacts with the fat, creating dancing patterns.
Hydrogen peroxide is no longer recommended for cleaning cuts, scrapes, and open wounds. While it kills bacteria, it is not specific and also destroys healthy skin cells and tissue essential for healing. Additionally, it should not be used for acne, as it can dry out and irritate the skin.
When creating a cleaning solution for tile floors using ½ cup of baking soda and a bucket of warm water, essential oils can be included to give the mixture a nice scent." But, there's another benefit to using your favorite essential oil to leave behind a better smell after mopping.
Yes, you can absolutely mix baking soda and hydrogen peroxide. Combined, they create a highly effective, non-toxic cleaning paste that works wonders on kitchen stains, tile grout, and burnt-on food.
