ID Code: F2-07
Purpose: Show the difference in density between soft drinks with and without sugar.
Description: Unopened cans of Pepsi and Diet Pepsi are floated in water. The Pepsi sinks, while the Diet Pepsi floats. The density of the Pepsi is increased by the dissolved sugar, which occupies space between the water molecules. Diet Pepsi has no additional sugar, and is therefore less dense.
Availability: Available
