Over the past few weeks, Year 4 have been learning about volanoes. We have also designed our own volcanoes to make them erupt with flowing lava. If you made your volcano but didn't have the time to make them erupt then why not follow the recipe below to complete at home?
Red food colouring
Fill the container almost to the top with warm water. Add a few drops of food colouring. Squeeze 6 drops of detergent into the bottle. Add two tablespoons of baking soda. Slowly pour vinegar into the bottle. Your volcano will fizz and spurt red lava!
Why does this happen? Can you find out?
