### Why Does This Happen?

Each soft drink has the same volume… i.e. 375mL
However, they each have a different mass… weigh each one if you want!

Density is a measure of mass in volume… i.e. how much stuff is packed into a given space.

Regular soda drink contains a large amount of sugar, making it denser than the diet soda drink. The diet soda floats above the regular soda because it is less dense.

The diet soda most likely contains a small amount of artificial sweetener called Aspartame. Aspartame is 200 times sweeter than sugar so you don’t need much.

Whether you eat entirely natural foods or those with partly artificial ingredients, food technologists has played a part in developing those products. In fact, nearly every food you eat has been selectively bred over thousands of years.

### Variables to test

More on variables here

• Hot vs. cold water… does it affect how well the cans sink or float?
• What happens when you use different soda drinks?
• If you shake the drinks, does this make a difference?
• What if you use a liquid other than water to repeat the experiment?
• What about different volumes of cans? Does using bottles make a difference?
