Holds coloured liquid for visual demonstration of fluid behaviour during rotation
Compatible with
Electrical rotating platform, water jet apparatus, falling water apparatus
Water is added to the bowl and a little dye mixed in, then the bowl is set in place on the rotating platform or next to the water jet or falling water set-up. As the platform speeds up, students watch the coloured water change its flow pattern, which helps explain how rotation and the centrifugal effect act on a liquid.
