Abstract
A cylindrical toy having a first and second half each defining a semi-cylindrical body. Each of the halves has secured to its inner surface a plurality of substantially semi-circular flat plates which define a spiral passage when the halves are connected. The cylindrical halves have a bottom portion and the bottom portion of one half includes a bottom guide disk. The second half includes a reinforcing plate which is spaced from and disposed parallel to the bottom portion of the second half to form a space which receives the guide disk of the first half in order to accurately position the two halves with respect to each other prior to their being connected together.
