This science experiment is simple enough for children to try independently. You can use one lemon or a few, but it best to use a selection of food colouring to make it extra exciting. Children will investigate a fun fizzing reaction caused by mixing acid (lemon juice) and base (baking soda). Once the baking soda and citric acid have neutralized each other, the reaction will stop, so eventually, your volcano will stop erupting! #TheDadLab #playmatters #simplescience #steam #experiment | TheDadLab
