"In Cooling, a visiting inventor and two young islanders, Olive and Troy, try to beat the heat on a hot summer day by cooling off in the river -- only to find that the Island's mammoth population has already beaten them to the water and there's no room left for the humans! Olive suggests that they build a machine to create a breeze for them. After tinkering in the inventor's workshop for a time, they apply what they learn about how refrigerators work and wind up building some machines that are really cool -- with no mammoths necessary!"--Producer's website
