In this how-to video, you will learn how to stack liquids at home. This will make for a great experiment. You will need a tall, transparent container, molasses or honey, liquid soap, water, vegetable oil, and rubbing alcohol. You might want food coloring and items to float in the container. First, add the molasses to the container. Next, add the dish soap and water. You can add food coloring to this. Make sure to pour it on the side of the container. Add the vegetable oil on top of the water. Lastly, add rubbing alcohol on top of the oil. Food coloring can be added to this. You have now created a density tower. Add the objects to the tower to test their density. This video shows how easy it is to make your own experiments at home.
