Diet Soda Check - Density experiment Science fair project

Materials Required

2 cans of diet soda – unopened
1 normal soda
and the other diet soda
a jar of water

Procedure

Drop both unopened cans of sodas into the jar full of water. Observe. You would observe one can floating and the other sinking. The one with sugar sinks and the one without sugar (diet soda) floats

Inference

Diet soda does not use sugar instead a chemical called aspartame. Aspartame is 180 times sweeter than sugar. So, 1 tsp of aspartame is equal to 180 tsp of sugar. Hence for diet soda less weight of aspartame is enough to sweeten the drink when compared to non diet soda which uses regular natural sugar. That is the reason why when equal volumes (355ml) of 2 soda cans of normal and diet soda are put in water normal soda can sinks and diet soda floats. Diet soda can is less heavier (or denser) than the normal soda can.
