Best Salt Water Density Experiment Ever (Maybe) Full Experiment in Comments!

Add tons of salt to water and many nearly invisible layers of salt water of different densities form. But using food coloring and water balloons we can begin to visualize the layers that form. In this experiment we allow the salt water to concentrate and separate based on the density of the layers. Water Balloons filled with salt solution will sink to the level of the density of the solution they were taken from
