Buy Cascading Messy Station. Pour liquid into the top bowl and see it cascade and collect into the lower section. Children will love experimenting with this portable water play unit. The metal bowls can be tipped as we know children love emptying and filling their water containers. Incorporate the unit into various play activities using large trays, funnels, channels, buckets, scoops, jugs etc. A lovely way to encourage investigative skills and add something different to sand and water.
