Manipulative egg-shaped puzzle

An amusement device comprising:

• (a) a first housing having a transparent window and a movable slide with projections thereon extending internally of the first housing;
• (b) a second housing having a curved surface and being rotatably connected to the first housing;
• (c) an internal mechanism for rotatably connecting the first and second housings, the internal mechanism having:
• (i) a movable weight;
• (ii) a central hollow shaft extending between the second housing and the first housing for receiving the movable weight;
• (iii) a third housing having a color marking thereon and surrounding and being fixedly connected to the shaft;
• (iv) a movable means connected to the third housing and extending into the shaft for normally holding the weight in the first housing and releasing the weight;
• and
• (v) a plurality of rotation rings surrounding the third housing, each rotation ring having a color marking thereon and a movable means receptacle therein, wherein movement of the movable slide selectively prohibits rotation of one or more of the rings, and wherein alignment of all of the color markings at the transparent window causes the movable means receptacles to line up and to receive the movable means, thus removing the movable means from holding relation with the weight, allowing the weight to move through the shaft, changing the center of gravity of the amusement device and allowing the device to stand upright on the curved second housing.
