2B40.57 - Density of a Soft Drink

Code Number:
2B40.57
Demo Title:
Density of a Soft Drink
Condition:
Excellent
Principle:
Comparison of Densities
Area of Study:
Heat & Fluids
Equipment:
Can of Regular Soft (i.e. Pepsi, Coke), Can of Diet Soft Drink (Same Brand as Regular), Tank with Water.
Procedure:

Put unopened cans into the tank of water, the diet will float, while the regular one will sink.
