My kids love anything scientific. Reactions that they don’t expect amaze them and this baking soda and vinegar volcano experiment did not disappoint. This month Netflix is featuring a number of movies and shows that feature “science fair fun.” One documentary that is a great example is Deadliest Volcanoes: Nova, which showcases some of the most fascinating volcanoes from around the world. I really wanted to try experiment with the kiddos and I figured this would be a perfect opportunity – make the volcano and then watch the show.
What You’ll Need
For the volcano:
4 cups of all-purpose flour
2 cups of salt
4 tbsp of vegetable oil
2 cups of water
Brown gel food colouring
1 plastic bottle
1 baking pan
For the eruption:
Warm water to nearly fill your plastic bottle
10 drops of red food colouring
6 drops of dishwashing detergent
2 tbsp of baking soda
1 cup of vinegar
How To Make It
1. Make the dough for the volcano. Mix 4 cups of flour with 2 cups of salt. Add 4 tbsp of vegetable oil and 2 cups of water. Stir until well combined. If the dough is not smooth and firm, slowly add more water 1 tbsp at a time until you reach your desired consistency.
2. Once the dough has come together, add some brown gel food colouring and knead it into the dough until well combined.
3. Place an empty plastic bottle in the centre of a baking pan. Wrap your dough around the plastic bottle to create a volcano. Make sure you leave an opening at the top, where the opening in your water bottle is.
4. Fill your water bottle about ¾ full with warm water. Add 10 drops of red food colouring, 6 drops of dishwashing detergent and 2 tbsp of baking soda.
5. Grab a cup of vinegar and let your kiddos slowly pour the vinegar into the opening in the volcano and watch the magic happen!
How It Works
The combination of baking soda and vinegar create a chemical reaction. This reaction creates carbon dioxide gas which is also present in real volcanoes. When the carbon dioxide gas is produced, pressure builds up inside the water bottle. The pressure is released when the gas bubbles out of the volcano and creates cool red lava.
This super cool volcano is a classic science experiment that never gets old and will delight and amaze your child. Give it a try! I bet they’ll love it.
