A device is provided for establishing the uniformity of wall thickness for a plurality of hollow spherical shells suspended in a liquid. Specifically, the device imposes a variable angular acceleration on each shell in order to establish a uniform wall thickness for each shell. The device includes a container for receiving the liquid and the suspended shells. Further, the device includes a motor for moving the liquid to impose a variable angular acceleration on each shell. Also, the device includes an element for polymerizing each shell after each shell's wall thickness has become substantially uniform.
