on Earth that exists in Gas/liquid/solid. To make Fireworks, fire needs Fuel(Water, Paper, and Plastic) , heat and oxygen, Why do you need these things to make fire?. Paper lifts when air is blown across the curve because of air pressure. When you rub your hands it creates heat and when you click your fingers it makes sound and that's friction. Inside a nappy is a powder chemical called Polymer which turns liquid into solid. Chemical reactions are when you mix 2 or more things together - changes the state. These are all the things that we learned at the science show.
