Making Layered Liquids Follow FizzicsEd 150 Science Experiments: Comments 0 You Will Need: 50mL Vegetable oil 50mL Glycerol or Glucose syrup 50mL Water, coloured with food colouring. Shaving cream Clear Plastic container Beads, marbles and foam Copyright Instruction Video Instruction 1 Pour the glycerol (or corn syrup) into the bottom of the plastic container. Try not to touch the sides. 2 Carefully pour the oil down the side of the container. There should be two distinct layers. 3 Now carefully pour the water down the side of the container. Where did this layer end up floating? 4 Carefully place the beads (etc.) onto the surface of your layered liquid. Where do they float? Why? 5 Add some shaving cream on the top! 6 Get the Unit of Work on Mixtures here! How can we separate mixtures? What are the different techniques?

Density = Mass / Volume. The higher the density, the more compact the substance is, e.g. Iron is denser than water. The corn syrup is much denser than water, so the water floats above it. The water is more than the oil but less dense than the corn syrup, so it floats in between the oil and corn syrup. Finally, the shaving is the least dense of all the materials… so it sits above the three liquids. Actual densities Corn Syrup = 1.37g/ml Water = 1.00g/ml Oil = 0.91g/ml Shaving cream = approximately 0.80g/ml Questions to ask students: Is the vegetable oil more or less dense than the water? Why do some objects sink and others float? Weird Fact: The planet Saturn is less dense than water. A big enough ocean could make it float! Solid water (ice) floats because it is less dense than water as a liquid. Very unusual for a chemical. Variables to test More on variables here Try adding different liquids to produce an even great array of stacked colours. What happens if you add sugar or salt to the solution? What happens if you add cold vs. warm liquids into the mix? What happens if you shine a spotlight at the side of the density column? Learn more!
