Density Demo: Coke VS. Diet Coke

Our density demo today....we tested coke vs. diet coke (or regular vs. diet soda) and found that the regular sodas sank, whereas the diets all floated. When we measured out the amount of sugar in an average regular soda (anywhere from 39-55 grams of sugar) vs. the equivalency in non-calorie sweetener (we used Splenda) the kids were totally grossed out! Our conclusion was that the regular sodas were more dense (we talked about an elevator packed with 20 people, vs. an elevator which held only 2 people), therefore sank to the bottom. Pretty fun!
