What does the elephant toothpaste experiment show?

What does the elephant toothpaste experiment show?

The foam you made in this classic Elephant’s Toothpaste reaction is extra-special because each tiny foam bubble is filled with oxygen. Your experiment created a reaction called an Exothermic Reaction – that means it not only created foam, it created heat!

What is a good hypothesis for elephant toothpaste?

My hypothesis is that the reaction will have a greater production of bubbles when used with the 3 oz dish soap. This is my hypothesis because the dehydration of hydrogen peroxide produces oxygen, which makes the dish soap foam up.

How do you make elephant toothpaste safe?

Procedure

1. Measure 1/2 cup of hydrogen peroxide, and carefully pour it into the bottle.
2. Add a big squirt of dish soap into the bottle, and swirl gently to mix.
3. If you want to make your foam a single color, add a few drops of food coloring directly into the hydrogen peroxide, and swirl the bottle gently to mix.

Can you make elephant toothpaste at home?

1/2 cup 20-volume hydrogen peroxide liquid (20-volume is a 6% solution; you can get this from a beauty supply store or hair salon) 1 Tablespoon (one packet) of dry yeast. 3 Tablespoons of warm water. Liquid dishwashing soap.

Will 3 peroxide work for elephant toothpaste?

What is Elephant Toothpaste? This large demonstration uses hydrogen peroxide (H2O2), sodium iodide (NaI) and soap. That is usually 3% hydrogen peroxide, and your local salon probably uses 6%. The 30% hydrogen peroxide is not something you would put on a cut or scrape, but it works perfectly for this demonstration.

What is the best catalyst for elephant toothpaste?

The secret ingredient is actually sodium iodide, which acts as a catalyst (something that speeds up a chemical reaction, and in this case, it’s the decomposition of hydrogen peroxide). When hydrogen peroxide (H2O2) decomposes, it breaks down to form water (H2O) and oxygen (O2).

Is Elephant toothpaste flammable?

Re: Elephant toothpaste I see it now. What is happening is that the reaction is generating pure oxygen, which is a highly flammable environment.

What is the constant in elephant toothpaste?

Constants: The constants in my experiment are the catalyst (dry active yeast), the temperature (room temperature and warm water for catalyst activation), setting (same sink), amount of hydrogen peroxide (4 oz in both bottles), amount of food coloring (4 drops), and type of container (20 oz Aquafina water bottle).
