About this item

• Recreate one of nature's most awe-inspiring events. Kids will have heard about volcanoes and seen images of their spectacular displays but how do they work? Use the volcanic eruption kit to teach children about volcanoes and chemical reactions in a fun and visual way.
• An interactive activity that the whole family can participate in. The kit comes with instructions and is simple to use. Combine the acid and baking soda to begin the chemical reaction
• The acid present in the tartaric acid reacts with the sodium hydrogen carbonate in the baking soda to produce carbon dioxide. This causes the mixture to bubble up and 'erupt' out of the volcano like lava. The addition of the red food colouring gives it a look of real lava.
