This simple and fascinating dry ice experiment uses only a few items but creates a magnificent reaction. Watch how the ice turns into a gas and produces a smoky or steamy effect. It may remind children of an erupting volcano or even a steam train. Even though it produces a wonderful gassy reaction, it is not hot like you may think it would be. Perfect for the children to get involved in! ⭕ Materials: - Water bottle (with a sports cap) - Dry ice - Gloves - A cup of water - Food colouring - Funnel
