Lots of people love fizzy drinks, so why not use a science experiment and try making your own? This experiment can demonstrate the power of carbon dioxide while leaving behind a tasty fizzy drink at the end! Give this one a shot to understand what's going on inside those fizzy drink cans a little better.
Materials 1-2 lemons
A drinking glass
1 teaspoon of baking soda (make sure this is baking soda, not baking powder)
1-2 teaspoons of sugar to sweeten the drink
Juice the lemons, then strain the lemon juice into a drinking glass.
Add water and stir to combine. Use about the same amount of water as the amount of lemon juice so that you almost double the amount of liquid in the glass after adding water.
Pour a teaspoon of baking soda into the glass. Give it a quick mix to make sure all the baking soda is dissolved.
Watch as the baking soda makes the water and lemon juice mix bubble and roll up the glass!
This stage may get a little messy, so be prepared with a dish cloth to clean up if the bubbles bubble over the top of the glass.
Wait for the bubbles to settle, then add some extra sugar and mix it through. This will add some sweetness to the drink and make it more drinkable. Give the drink a taste, then add more sugar if needed.
How it works
The resultant bubbly mixture you have created should taste a little like lemonade or lemon flavoured soft drink!
When the baking soda is added, a chemical reaction occurs that makes bubbles of carbon dioxide form in the lemon mixture. These are the same type of bubbles that form to make real soft drinks! In the case of canned or bottled soft drinks, the bubbles are contained within the can or bottle and kept fresh so that, when you open the can or bottle, the drink inside is fizzy. The carbon dioxide starts to escape while the container is open, so gradually the drink will lose its fizz.
The chemical reaction happens when lemon, which is an acid, reacts with the baking soda, which is a base. The main product of this reaction is carbon dioxide - bubbles!
