Pluï Rain Ball. The Pluï rain ball is undoubtedly the best water toy for the bath or swimming pool. Pluï stands out because of its beautiful design and fun colours. The ball arouses curiosity, stimulates the senses and teaches children to get used to a shower jet. The ball has funny protrusions on the bottom and one larger opening on the top. Dip the ball under water to fill it. When you bring the ball above the water, you get a nice, soft rain shower. The trick is to keep the water jet under control by covering the hole at the top with your fingertip and leaving it open again. In this way, children learn about the basic physical principles of air and water in a simple and playful way. Diameter: 8.5 cm Colour: Yellow
