Red, White and Blue II Demonstration

In this chemistry demonstration, learners investigate the rule "likes dissolve likes" by combining three, immiscible liquids to create a colorful density column. Learners are asked, "What color will result from mixing red, white, and blue?" They will be surprised by the answer as a beaker is revealed with red syrup on the bottom, white milk over the syrup and blue lamp oil on top. This is a perfect activity to use to demonstrate density and polarity, especially around the 4th of July.
