Complete with fish that bob up and down in the bubble stream, it is ideal for sensory rooms or quiet rooms. Provides a calming wash of light as they morph through colours. The fish are superb aids to measure and improve eye tracking in young children, a key skill in literacy and reading. Bubble Tubes should be regularly cleaned and the water replaced to help avoid the build-up of algae or mould. Complete with adapter. Adult supervision recommended because children should not play with the Bubble Tube directly as it is not a toy. Bubble Tube stands 1m high.
