Step 3

Fill one of the bottles one-third with vinegar. You can use the funnel to fill the vinegar into the bottle. After that, add a few drops of food coloring and one tablespoon of washing liquid.

Step 4

Keep the second bottle on top of a plate. Into this, add around 3 tablespoons of bicarbonate of soda using the funnel. Set the cone shape on top of this bottle. While placing the cone shape, make sure that the opening of the cone shape is on a level with the opening of the bottle.

Step 5

Using the funnel, drop in the vinegar, and washing liquid mixture into the second bottle. Try removing the funnel. What do you see? Your own bubbling vinegar volcano!

The Science Behind the Vinegar Volcano

The food coloring is added in order to create a unique coloring for the volcano lava. You can always use brown coloring but you can even try experimenting with different colors.

The bicarbonate of soda and vinegar mix together to form carbon dioxide gas. This is what makes the mixture foam and expand out of the bottle.
