Detailed explanation-1: -Coke and Diet Coke cans have the same amount of liquid in them. But Diet Coke cans float and regular Coke cans sink. This is because Coke is a denser fluid than Diet Coke.
Detailed explanation-2: -Due to the difference in density, the can with the sugar in it sinks while the diet can floats.
Detailed explanation-3: -Our own rough experiment-weighing different volumes of liquid in a graduated cylinder-gives an average density of 0.911 g/mL for Diet Coke, and 1.026 g/mL for regular Coke.
Detailed explanation-4: -Diet Soda Can < 1.0 g/mL (water) < Regular Soda Can < 1.16 g/mL (Salt water) Extremely “hard” tap water can have a density significantly higher than 1.0 g/mL This can cause even the regular cans to float!
