A chemical reaction occurs when substances are mixed together and are changed. Sometimes substances mix together and not much happens. Other times the results are pretty dramatic. Today we will look at a chemical reaction. We will mix two substances together. Then we will add a catalyst. Adding a catalyst when you mix two substances together makes the reaction happen faster. It turbo-charges the reaction! Watch the video below for a fun demonstration of a turbo charged chemical reaction. You can probably find the things you need to try this one yourself at home!
What You Need:
- Plastic Soda Bottle
- Hydrogen Peroxcide
- Measuring Cup
- Dish Soap
- Food Coloring
- Dry Yeast
- Hot Water
Pour a cup of hydrogen peroxide in the liter soda bottle. Add a few drops of food coloring and a few drops of dish soap. In a separate bowl mix 1 teaspoon of yeast with two tablespoons of hot (not boiling – just use hot water from the faucet) water. Use the funnel to pour the yeast mixture into the mottle. Stand back!!
- HINT #1 Do this one OUTSIDE!
- HINT #2 If you want your geyser to spew more, use a plastic soda bottle that is smaller than a liter – a bottle that is smaller will have more foam shoot out of it.
