Carbonated liquids have different amounts of carbon dioxide. Using raisins as a measuring tool, I will find out which liquid has the most carbonation. The bubbles will attach to the outside of the raisin and lift it up. Therefore, the purpose of my project is to find out which liquid makes the raisin rise to the top fastest.
- 5 clear 8 oz. plastic cups
- 24 oz. Canada Dry Ginger Ale
- 24 oz. Black raspberry flavored Ice
- 24 oz. Sprite
- 24 oz. Seltzer water
- A stopwatch
- 16-20 raisins about the same size
Step 1: Pour 6 oz. of Ginger Ale into one of the plastic cups.
Step 2: Take a raisin and drop it in the cup, at the same time also start the timer.
Step 3: As soon as the raisin floats all the way to the top of the cup, stop the timer and record the time.
Step 4: Take the spoon and scoop the raisin out of the cup, and put it on the plate.
Step 5: Repeat steps 1-4 three more times with Ginger Ale.
Step 6: Then, repeat steps 1-5 with the rest of the liquids.
How it Works
The carbonated drink has carbon dioxide bubbles that attach to the rough surface of the raisin. When enough bubbles attach, the bubbles float up to the top lifting the raisin. Then the bubbles pop, when they get to the surface of the beverage. So the raisin floats back down to the bottom, and the process starts again.
