Why does mentos make soda fizz and what kind of soda fizzes the most. The hypothesis is, the diet soda will fizz more because of the extra carbonation from the fake sugar. The diet soda did go higher than the regular for a short period of time at 3 inches, what was noticed was that it fizzes longer at the middle of the bottle. The regular soda fizzed about an inch in the air for longer than the diet and did not fizz after finishing its launch out of the nozzle of the bottle. The findings of last night proved that the one that fizzes longer was diet and the one that fizzes the most was diet. Diet was clearly the winner in this.

Regular Cola Carbohydrates: 41 grams Diet Cola Carbohydrates: 0g Variables: Dependent Variables: The height of the spray of soda produced, how big clean up was going to be. Independent Variables: Choice of soda and number of mentos. Constants: Volume of soda, shape of bottle, temperature of soda, mentos' style of entry.

Procedure:

1. Put 3 mentos into the diet Soda 2. Write results or draw a picture diagram. 3. put 3 mentos into the regular soda 4. write results or draw picture 5. Compare findings on height of the fountain and time fizzing. 6. Conclude if your hypothesis was correct.

To control this experiment i recommend a table that can be hosed off easily. Do it outside and make sure you don’t shake the bottle before. The explosion will get weaker the more carbonation that leaves the bottle so make sure to only have a few seconds between opening the bottle and putting the mentos in.

Safety: You will need gloves to save yourself from stickiness. If you want goggles to protect your eyes from the soda it is not needed but optional.

Materials: You will need mentos, diet soda, regular soda, a table outside and a hose for clean up.

Background Info:

[|__http://www.eepybird.com/featured-video/coke-and-mentos-featured-video/science-of-coke-mentos/__] Mentos was opened in 1948 as a mint company until someone discovered it could be used to fuel soda into rockets and fountains. Lee Marek and "Marek's Kid Scientists" performed the Diet Coke and Mentos experiment on the Late Show with David Letterman in 1999. They were one of the first to demonstrate it on tv.
