Episode #4: Sinking & Floating

This episode was all about things that sink and float: the basic ideas of buoyancy. We looked at ways to make bowling balls, balloons, bubbles, pop cans and ketchup packets all float and sink. Some highlights include: watching bubbles float over dry ice, making helium bubbles, dancing raisins, and making hot air balloons at home.
