Okay, so I’m doing an experiment on which type of foods mold the fastest. for my experiment i used a cup of milk, a banana, a slice of bread, and a slice of cheese.
i put all of the foods in a plastic bag last friday ( March 21,08) and put them in a dark room temperature cabinet.
For some reason my foods haven’t rotten yet, they all look prfectly fine. And the expirement was supposed to take 4-5 days, and its almost a week now. could it be because i put the foods in the plastic bag (and milk in a cup with the top ceram wrapped) and this probably preserved the food? plz help me!!!!
