DIY Density Column

We know that density depends on mass and volume of a substances. We can easily see differences of density when comparing anything to the air in our atmosphere. But what about common liquids compared to each other? Lucky for you, that’s exactly what we did. In this DIY experiment we poured seven liquids into one container to see what would happen.

Density pour

The seven ingredients that we are using are honey, corn syrup, maple syrup, whole milk, dish soap, water, and vegetable oil. Just to spice things up we added a bit of food coloring to the water. If you pour them in order of most dense to less dense, they do a really good job in staying separated. However, the food coloring that was added to the water turned out to be more dense than water and the dish soap and started mixing in with the milk layer!

Ideally, if we mixed up the density column and incorporated all of the ingredients together, after a few hours we would be able to get the layers back. However, the dish soap will react to the milk and oil, making separation impossible for every single layer.

We tried this experiment with just seven liquids. Can you think of other liquids to try adding? When you do this at home, try dropping in different household items like paper clips, bottle caps, or ping pong balls to see how their densities compare.
