21 Sep Chemical Volcano – Children’s Science Experiments
Some Science party companies use the chemical volcano demonstration for an awesome chemical reaction. But with a few kitchen ingredients you can make exactly the same Chemical Volcano at home – for pennies!
Before you begin :
PLEASE ENSURE YOU HAVE ADULT SUPERVISION AT ALL TIMES.
Important! Do NOT look down the volcano. DO NOT eat, put on clothing or your carpet! In case of accidental contact with either, just use a damp cloth, a little soapy water and gently rub gently.
Make sure that you’re wearing protective clothing, eye glasses and working in an area where you can clean the ingredients easily.
The Chemical Volcano – Let’s begin…
Ingredients and equipment
• A tablespoon
• Baking Soda – please make sure it’s not baking powder
• A container to hold the reaction
• Liquid food colouring (optional)
• One plastic cup
• Bottle of Vinegar
• Plenty of paper towels to clean up the mess
Step 1. Measure approximately 1 heaped tablespoon of baking soda into the container.
Exact measurements are not that important. Just try and get it close.
Step 2. Add about 1 or 2 drops of food colouring into a plastic cup.
Step 3. Pour some vinegar into the plastic cup – approximately half a cup. Gently mix the vinegar and food colouring using a tablespoon.
Now the fun part…
Step 4. Pour the contents of the plastic cup into the container and watch the reaction!
Did your volcano work? Was it easy to find the ingredients? Was it easy to follow the steps? How long did your chemical reaction last? What happens when you add another heaped tablespoon of Baking Soda?
The Baking Soda is a base and the vinegar is a weak acid. When you add the vinegar to the Soda powder they react to form Carbonic Acid, which is very unstable. This new acid breaks down into water and carbon dioxide – or the fizz!
