Day of Experiments in scientific method form Design #1

Hypothesis: If a drop 4 mentos into a 8oz. bottle of Diet Coke which was pour from a 2 L bottle then it will cause a chemical reaction which results in a a stream of C02 bubbles.

Procedures:

1.       Gather a 2 L bottle of Diet Coke,  a sleeve of Mentos and a 8 oz. empty Diet Coke bottle
2.       Pour 8 oz. of Diet Coke into the 8 oz bottle.
3.       Let rest for a minute 
4.        Drop 2 Mentos into the bottle

Results

When dropping the Mentos into the pre-poured 8 oz. Diet Coke bottle, no reaction happened. To check results, 4 Mentos were dropped into the remainder of 2L bottle, a stream of bubbles erupted from the bottle,

Conclusion

The experiment was a failure.  In trying to save Coke and do as many experiments as possible I poured the soda into another bottle. The problem with that is all the gasses that make the reaction occur are released when being poured. When I poured a small amount of Diet Coke into the bottle and then put Mentos into it the gasses where gone and no reaction occurred. . I decided not to use Design#1 for two reasons. One: I would never be able to test my experiment on the actual bottle that I would use in the testing. Two: the amount of Diet Coke and Mentos I would need to do experiments and test would be too much and I would be wasting it.
