3.3 Special observations
The results were inconsistent and it was hard to explain why. For example the marble chips in the tea and coffee samples increased in weight for the first day but the results fluctuated after that.

The first experiment could not be continued and had to be terminated on the 2nd day due to mould growth on the coffee and tea. This had reminded us that we had to take possible mould growth as a consideration when handling perishable items in experiments. Thus, we added bleach to the beverages when conducting our second experiment, as well as refrigerating the samples.
