This activity will prove that Mom was right… “Wash your hands with soap and warm water!” A Petri dish prepared with nutrient agar (a seaweed derivative with beef nutrients) is an ideal food source for the bacteria you’ll be growing. In this experiment, Steve Spangler collected samples from items around the office – you will not believe what he found.
