Swimming Raisins




I chose this experiment because, knowing that raisins are heavy, I wanted to see just how easy they could float.


This experiment worked because, when I mixed the vinegar, water, and baking soda together it createda chemical reaction, where a gas is produced, which makes many, many, bubbles. A carbon dioxidegas is produced. When the bubbles are filled with the gas, they are lighter. These bubbles carry the raisins to the top.
