A rain ball for bath or pool - Plui is one unique little creature. Immerse Plui in water to fill it up and then plug your finger over the top hole as you raise it up high. Lift your finger from the hole and water falls like rain. Plug it up again and instantly, it stops. (Yes, like Zeus, you control the rain!) A basic principle of physics becomes fascination for the senses and inspiration for the imagination with Plui.
