Mentos and coke science fair project
It is important to repeat your experiment so that you are sure that your results are repeatable and reproducible. Maybe you did this in a volcano model? Repeat steps 1a to 1c two more times so that you have three groups of candy pieces. Mentos candy pieces are covered in tiny dimples a bit like a golf ballwhich dramatically increases the surface area and allows a huge amount of bubbles to form.

The boys wanted to test size of the bottle, type of soda, and number of Mentos. Large bottle of Diet Coke About half a pack of Mentos Geyser tube optional but makes things much easier Instructions: Make sure you are doing this experiment in a place where you won't get in trouble for getting Diet Coke everywhere. Remove the used Diet Coke bottle and set it aside. This means that there is a whole lot of carbon dioxide gas just waiting to escape the liquid in the form of bubbles. Courtesy of www. To prevent soda from possibly splashing the camera or volunteer, do not place the video camera too close to the testing spot. I also found that Diet Coke that had been bottled more recently worked better than older bottles that might have lost some of their fizz sitting on shop shelves for too long, just check the bottle for the date. When the bottle stops spouting, stop recording.
Now you are ready to watch your videos and analyze your data. Dropping something into the Diet Coke speeds up this process by both breaking the surface tension of the liquid and also allowing bubbles to form on the surface area of the Mentos.
Place a piece of wax paper on top of the cutting board. Time for the fun part, drop the Mentos into the Diet Coke and run like mad! Is the geyser taller?
