Science Experiment: Does The Liquid The Boat Float In Affect The Number Of Pennies The Boat Can Hold

We did an experiment to find out if different types of liquid affect the number of passengers ( pennies ) a boat  (paper cup) can hold. The different liquids we used were : Normal water, hot water, salty water, soapy water, soda. We thought that the soda would affect the amount of passengers the boat could hold because the bubbles would lift and keep the boat at the surface of the liquid in the tub. It turns out that the soda did hold the most pennies.
