Soda and other fizzy drinks are made in pretty much the same way: carbon dioxide is dissolved in water under pressure. When you open a can of a carbonated drink, the CO2 comes out of the solution. First comes the whoosh when the pressure is released. Then comes the bubbly fizz when the carbon dioxide floats up through the liquid and into the air. | The Interaction of Atoms and Molecules | Kids Discover
All matter is composed of atoms. Atoms are so small that millions of them can fit on the head of a pin, yet atoms are themselves made up of even smaller parts: electrons, which are particles with a negative electrical charge; protons, which are positively charged particles; and neutrons, which have no electrical charge. A particular atom will have an equal number of protons and electrons. From our Topic What Is Matter? | Kids Discover
