How to Make a 9 Layer Density Column [Video]

By Jason Fitzpatrick on October 10th, 2012

Density columns, layers of varying density liquid in a glass cylinder, are nothing new in the world of science demonstrations, but this nine layer one with seven floating objects is something to see.

Courtesy of Steve Spangler Science, the experiment goes above and beyond the traditional five layer column by adding another four layers and sinking objects of varying density into the column. The end result is a colorful demonstration of the varying densities of liquids and solids.

If it can be modded, optimized, repurposed, or torn apart for fun he's interested (and probably already at the workbench taking it apart). You can follow him on if you'd like.
