Question

Did you know that an unopened 355 mL can of diet Dr. Pepper will float in a lake? That’s a fact! However, it’s also a fact that an unopened 355mL can of regular Dr. Pepper will sink in that same lake! Based on these two facts, which type of soda is the least dense? Explain your answer.

Answer 1

Regular Coke/Pepsi has a higher density than water, so a can of it sinks in water. Diet Coke/Pepsi has a lower density, so a can of it floats.
