If the weather is getting a bit warm for you how about we cool everything down with an Ice Volcano! Oh, and learn a thing or two about chemical reactions too.
What do I need?
How do I do it?
STEP1 – Our first step is to build our Ice Volcano. Take a container of baking powder (approx 150g) and mix together with some warm water in a bowl.
STEP2 – Keep mixing your baking powder and warm water together until most of the baking powder has dissolved.
STEP3 – Let’s freeze our Ice Volcano! Gently place your bowl full of water mixed with baking powder in the freezer and leave overnight.
STEP4 – Take the Ice Volcano out of the freezer and let it warm up for 5 minutes before turning it over onto a plate.
STEP5 – Use different food colourings to colour our white vinegar.
STEP6 – Eruption! Add the coloured vinegar to your Ice Volcano and witness the eruption!
What’s going on?
Your Ice Volcano is a perfect example of the classic acid + base reaction. As our Ice Volcano is made from baking powder it is a base (or alkali!). The vinegar that we add is an acid. When we mix the acid and the base (vinegar and baking powder) we get a chemical reaction. Those bubbles that you can see are bubbles of carbon dioxide.
More Fun Please! - Experiment like a real scientist!
What’s the perfect quantity of baking powder to make the most active Ice Volcano?
What could you use instead of white vinegar to trigger your volcano?
Try using regular brown vinegar or some lemon juice on your Ice Volcano. What difference does that make?
