Hello, in science class we were assigned to do an experiment. We had a big bowl of cold water, and a little jar of hot water in side it with food coloring, and after the jar, we had plastic aluminum foil. That jar was stuck to the bottom of the big bowl and sprinkle pieces of paper on the cold water. And then we made 2 wholes in the aluminum foil. During this lab i have realized that once we made the wholes, the pieces of paper moved. That happened because we made the wholes, the warm water mixes with cold and made little currents which moved the pieces of paper.
