Additional Details

Make demonstrating density fun with the Color Column! Simply add dye to the required liquids and pour each component into the graduated cylinder. Students will observe each layer remaining separate as their differing densities cause them to float one on top of the other. The entire classroom can engage in scientific inquiry by submerging small objects and comparing their densities based on where they halt within the column. This visually striking demonstration is a must for teaching density.
