This simple density science experiment starts with placing two glasses with yellow water on top of two glasses with blue water. When we remove cards that separate coloured water, colours on the right do not mix, but they do mix quickly on the left. Magic secret hies in the temperature of the water. Hot water is less dense than cold water, so it rises to the top as oil would. But in case hot water is already on top, it does not move anywhere, and colours do not mix #TheDadLab #playandlearn #scien

Simple density experiments you can try in your kitchen now. We started by putting a glass of water on top of a glass of vegetable oil. That is a cool experiment on its own, but let's focus on density here. After we moved the card that separated glasses a little bit to create a small gap for liquids to connect, water and oil started moving. In the end, we had oil in the top glass and water in the bottom glass. It was time to turn our structure upside down and watch the flow of these liquids again
