To perform our little experiment you ll need a can of regular soda of any brand and an equivalent can of the diet version say coca cola and diet coke for example.
Coke diet coke float experiment. In high school my physics teacher took two cans of soda from a vending machine plopped them in an aquarium filled with tap water and blew our minds. It s absolutely free. So naturally when i mentioned this density and buoyancy experiment or demonstration his interest was piqued.
Why do diet soft drinks float and regular soft drinks sink. Ob serve the re lease of gas and for ma tion of a spout of foam. Try the experiment again using salt water.
Water has a density of 1 g ml g cm3. Toss a men to into a bot tle of diet coke. The diet coke will float at the top and the coca cola will sink to the bottom.
Density is a measure of the mass per unit volume of a substance. This is also a slow process but after a day you can see the breakdown of the protein in milk which has been curdled at the bottom of the bottle. Objects will float in water if their density is less than 1 g ml.
Pour 50 ml coca cola into 30 ml milk. The 40 grams of sugar added to a can of regular soda make it sink and the relatively tiny amount of artificial sweetener used in diet soda has a negligible effect on the mass enabling the can to float. The coke can and the other cola can contain much more sugar which adds to the weight and therefore they sink in the tank.
This happens because of the sugar content in both cans. My son is a huge science buff. Density is the key to this experiment.
