▶️ How to make a seven-layer density column:
Step 1: Start with an empty, tall glass container. The size of your container will determine how many and how much of each liquid to add to form your layers. It's best if each layer is at least 1 inch thick.
Step 2: Pour honey into the very bottom of the container using a kitchen baster to create the first layer. Be careful not to get any honey on the sides of the container as you add the honey.
Step 2: In a separate container, mix food coloring with corn syrup (we used yellow), and then add on top of the honey using the baster.
Step 3: Add dish soap (we used Dawn that was already a green color) using the baster, and again avoid hitting the sides of the container.
Step 4: In a separate container, mix food coloring with water (we used red). When adding the water layer to the container, change tactics to let the water drip down the side out of the baster instead.
Step 5: Add a vegetable oil layer in the same way as the water step above. We did not use food coloring in our vegetable oil layer.
Step 6: In a separate container, mix food coloring with add 91% isopropyl alcohol (we used blue), and add the second-to-last layer via the baster method down the inside wall of the container.
Step 7: Add lamp oil (we purchased a red oil - food coloring will not mix with lamp oil) as your final layer.
Step 8: You're now ready to test the density of various objects using the column. We tested a metal screw, a grape tomato, a plastic bottle cap, and a ping pong ball.
▶️ How the density column works:
As you go from top to bottom the layers, become denser and denser, preventing them from mixing together. Different objects will stop at the different layers based on their density, floating suspended in the column.
