Mixing these two common kitchen substances causes a chemical reaction that produces carbon dioxide.
Carbon dioxide is a clear, colourless and odourless gas, but you will see the fizz produced when the powder mixes with the liquid, it should foam up quite nicely.
If you use a balloon, it catches all the carbon dioxide neatly, and shows just how much gas can be produced from such a simple reaction.
