Volcano Experiment in the Hive

Baking Soda & Vinegar Volcano
Use baking soda and vinegar to create an awesome chemical reaction! Watch as it rapidly fizzes over the cone of the volcano.

What you'll need: Baking Soda (make sure it's not baking powder) Vinegar Red food colouring A plastic drink bottle A container if you're doing this indoors to hold everything and avoid a big mess! Paper towels or a cloth (just in case) Instructions: Place bottle in vent of the sand volcano cone. Place some of the baking soda and food colouring into the bottle. Pour in some of the vinegar Watch as the reaction takes place! What's happening? - Extra Reading with Parents The baking soda (sodium bicarbonate) is a base while the vinegar (acetic acid) is an acid. When they react together they form carbonic acid which is very unstable, it instantly breaks apart into water and carbon dioxide, which creates all the fizzing as it escapes the solution.
