We wonder if other liquids can float on water? Can air float on water?

We made a wonderful concoction of water, dye, washing up liquid and cooking oil! We mixed it up and made it bubble as we swished it around with a paint brush! Some brave people blew bubbles with straws. 

We watched to see what would happen. We made our own observations about what floated on the top, what sunk and what mixed and dissolved in the water. Then we carefully lay paper across the top to make a print of the floating ingredients! What do you think was floating on the top? Why? We are going to explore these questions in class.
