This clothesline idea is something I would consider trying to incorporate into my classroom because while exploring with water children are simultaneously learning about daily life tasks such as bathing, hanging clothes, drying clothes, etc.
Water wall for sensory fun We used zip ties to attach tubs and bottles with the bottoms cut off to a peg board. We put the bottom in a tub with water, cups for pouring and balls. The children loved pouring the water through and seeing if they could catch it in another bottle. The balls sometimes blocked the water flow too and they could make the balls float in the water.
