Monster Toothpaste Recipe
By popular demand here is the Monster Toothpaste recipe that was at the first summer reading program. (What? You missed it? Sign up for the Summer Reading Club and join us next week.)
You will need:
- 1/2 cup 20-volume hydrogen peroxide liquid (20-volume is a 6% solution, which can be found at a beauty supply store or hair salon)
- 1 Tablespoon (one packet) of dry yeast
- 3 Tablespoons of warm water
- Liquid dish washing soap
- Food coloring
- Safety goggles
- Disposable gloves
For the home version:
- A clean 16 ounce plastic soda bottle
- Small cup
- Put on gloves and goggles. The concentrated hydrogen peroxide used in this experiment will burn the skin and eyes. It can also bleach fabric, so choose your clothing with that in mind.
- Pour hydrogen peroxide into the bottle. Using a funnel might help.
- Add 8-10 drops of food coloring into the bottle.
- Add about 1 tablespoon of liquid dish soap into the bottle and mix the solution by swishing it around.
- Mix the warm water and the yeast in a separate small cup for about 30 seconds. This activates the yeast.
- Mix with a spoon for 30 seconds, then remove any large lumps.
- Pour the yeast mixture into the bottle and stand back!
- This experiment cannot be done safely without goggles and gloves.
- The foam will overflow suddenly and quickly. Ensure this experiment is conducted on a washable, stain-resistant surface, and do not stand anywhere near the bottle or cylinder when it foams.
- The resulting substance is called monster toothpaste only because of its appearance. Don't put it in your mouth or swallow it.
- Monster toothpaste can stain.
