Toy water ball

Abstract

A toy water ball is disclosed. The toy water ball comprises a plurality of petals and a connecting member for connecting the petals, wherein each petal comprises a body and a rim extending inwards from the circumferential edge of the body. Each rim comprises magnetic members. The toy water ball has an open state and a closed state. When the toy water ball is in its closed state, the petals together enclose a water carrying cavity. The corresponding magnetic members on the two petals attract each other so the rims tightly abut each other, creating a water-blocking seal, sealing the water carrying cavity. The rims extend into the water carrying cavity. The magnetic members enables repeated open and close of the toy water ball. The toy water ball does not need a pressurized water source to fill with water.
