ABSTRACT:
A kaleidoscope includes a cylindrical barrel having a top open end and an opposite bottom open end and a top cover and a bottom cover, both having a circumferential wall to be force fit onto the top end and the bottom end of the barrel. The top cover has a hollow triangular frame formed on an inside surface thereof. The bottom cover has formed on an inside surface thereof a flake container in the form of a triangle inside which a plurality of colorful and reflective flakes and other small objects are received in a loose and movable manner. A transparent lid is also received within the flake container to confine the flakes inside the container. A recess is thus defined inside the flake container by the opening of the container and the transparent lid. A prism which is received within the barrel and has a first end fit into the triangular frame of the top cover and a second end fit into the recess inside the container of the bottom cover is releasably secured between the top and bottom covers. An observing window is provided on the top cover to observe the flakes through the prism. The prism defines a space with the barrel for storage of small articles which are received through a slot formed on the top cover. An access hole is provided on the bottom cover and is openably closed by a rubber plug.
