You lot will need

• A clean 16 ounce (473 ml) plastic soda bottle or a water bottle.
• 20-Volume hydrogen peroxide liquid (20-volume is a six% solution that is stronger than what y'all find in most pharmacies. Information technology is typically used for lightening pilus and is found at many beauty supply stores. You can use the iii% hydrogen peroxide plant in pharmacies, only the reaction volition be a fleck smaller)
• i Tablespoon (15ml –  one bundle) of dry yeast
• three+ Tablespoons (xv ml) of warm water
• Liquid dishwashing soap
• Food coloring
• Small-scale cup
• Funnel
• Safety goggles
• Adult assist

NOTE: The foam could overflow from the canteen, so exist sure to practise this experiment on a washable surface, or place the bottle on a tray.

CAUTION: The unreacted hydrogen peroxide can irritate skin and eyes. Read the safety information on the hydrogen peroxide bottle and be sure to wear rubber goggles.

What to exercise

1. Use a funnel to carefully pour 3/4 cup (180 ml) of the hydrogen peroxide liquid into the canteen
2. Add together about x drops of your favorite food coloring into the bottle.
3. Add most 1 tablespoon (15ml) of liquid dish soap into the bottle and classy the bottle effectually a bit to mix information technology.
4. In a separate pocket-sized cup, combine the warm h2o and the yeast together and mix for almost xxx seconds. It should be well-nigh the consistency of melted ice cream – add a bit more warm water if needed.
5. At present the run a risk starts! Use the funnel to pour the yeast-water mixture into the canteen and spotter the foaminess begin!

Tin can I touch the foam?
The reaction typically breaks down the hydrogen peroxide so y'all are left with generally simply soapy water and yeast. There tin, however, be un-reacted peroxide which could irritate skin and eyes. For that reason, it is recommended you lot do not touch on the cream.

(If you utilise the iii% hydrogen peroxide found in most pharmacies, then the foam tin can exist touched safely.)

How does information technology work?

Foam is awesome! The foam you fabricated in this classic Elephant's Toothpaste reaction is extra-special considering each tiny foam bubble is filled with oxygen. The yeast acted as a catalyst; a catalyst is used to speed upwards a reaction.  It chop-chop broke apart the oxygen from the hydrogen peroxide. Because it did this very fast, information technology created lots and lots of bubbles. Did you detect the bottle got warm? Your experiment created a reaction called an Exothermic Reaction – that ways information technology not only created cream, it created heat! The foam produced is merely h2o, lather, and oxygen then y'all tin clean it upwards with a sponge and pour any actress liquid left in the bottle downward the drain.

This experiment is sometimes called "Elephant's Toothpaste" considering it looks like toothpaste coming out of a tube, only don't get the foam in your mouth!

Make it an experiment:

The project to a higher place is a Demonstration. To brand information technology a true experiment, you can try to answer these questions:

1. Does the amount of yeast change the amount of cream produced?
2. Volition the experiment work as well if y'all add the dry yeast without mixing it with water?
3. Does the size of the bottle bear upon the amount of foam produced?
