Why Does Diet Coke Float And Regular Coke Sink

Some instructors have adapted this demonstration as an experiment to teach students the principles of density and buoyancy.

Why does diet coke float and regular coke sink. The artificial sweetener used in diet coke is hundreds of times sweeter per unit volume than regular sugar. The can of coke immediately sinks while the can of diet coke floats. It takes less artificial sugars to create the same taste like regular sugar so less is needed.

Diet drinks are less dense than their regular counterparts because the sweetener added to them is sweeter than sugar. But diet coke cans float and regular coke cans sink. Regular coke is much more dense than sugar free varieties.

Many science teachers perform a demonstration in which they immerse sealed cans of coke and diet coke in a tank of water. Diet coke pepsi has a lower density so a can of it floats. This is because coke is a denser fluid t.

Regular coke pepsi has a higher density than water so a can of it sinks in water. Coke and diet coke cans have the same amount of liquid in them. The diet coke doesn t have the sugar and the sweetening agent doesn t need to be added in large quantities.

That means in the diet there is less matter packed into the same space and it floats. This makes the density of the coke liquid greater than that of pure water so the regular coke sinks. Why does diet pepsi float and pepsi sink.

Cans of regular coke don t. This makes it less dense than the water and it floats. It is because diet coke has less sugar and density but the original coke has tons of sugar and more density.
