Default Diet Pepsi floats

Why does Diet Pepsi float and why does regular Pepsi sink?

Talking Cola Can Phenomenon

Well, contrary to the title above, this is no phenomenon. I did this experiment as a fun lab in my science course last year. The question was, "Why do some sodas sink when put in a cooler while others float to the top." Well, before actually conducting the experiment, each student had to come up with an educated guess/ theory on why this happened. Ideas varied from the amount of alluminom in the cans, to the amount of calories in the soda. After that, each student then brought in a can of their favorite soda and we put the theories to the test. We placed each can in a clear fishtank filled with ice water one at a time, noting if they sank or floated toward the top, or if they landed in the middle. Then we put them into classes based on the information found above. We then looked at all the similarities and differences in the sodas. (Most diet sodas floateds, whereas most fruit fllavored and regular sodas sank.) We found that the amount of sugar in a soda greatly influences whether it sinks or floats. We know this because sodas are flavored with syrups, which are heavy. The more sugar in the soda, the heavier the syrup was, causing the can to sink. The same thing for cans that floated, the less sugar, the lighter the syrup. So, in conclusion, Diet Pepsi floats because of the less amount of sugar in the syrup. Hope that helps! - BroadwayBaby
