Roo has been fascinated with the Hovercraft ever since he was small and we would read in his Big Book of Things that Go about how the “hovercraft travels over a cushion of air”. We’ve watched clippings on You Tube and he studiously examines the photo of the fire rescue Hovercraft in his Lego catalogue. In Japanese it is pronounced ha· ba - ku· ra· fu· to. Yesterday we did an experiment to simulate the action of floating on a cushion of air. While the concept of friction reduction is too hard to explain, Roo had fun telling me how the air flows down the balloon, through the bottle cap, and out the bottom of the CD. We experimented with the amphibious properties of the Hovercraft but the run in the bathtub was not successful. Roo continues to have a fascination with flow and likes to trace using diagrams that show the insides of something. For example, a picture of a vacuum printed from the Internet that he took to preschool when they were studying the “v” sound. This is why we sometimes call him “our little engineer”.
