Claim:
An automatic spinning device, comprising: a base having an inversed cup-like top member and a bottom member joined together and thereby forming a first space therewithin, said top member having a first flange and a second flange above said first flange around the circumference of said top member; a transparent lens positioned on top of said second flange and thereby forming a second space between said transparent lens and said top member; a first ring rotatably and horizontally positioned on top of said first flange, said first ring having a plurality of magnets positioned at equal spacing along the inner wall of said first ring; a second ring rotatably and horizontally positioned inside said first space at substantially the same height as said first ring, said second ring having a plurality of magnets positioned at equal spacing along the circumference of said second ring correspondingly to said magnets of said first ring, respectively, said magnets of said first ring having opposite polarity to that of said magnets of said second ring; said second ring having gear teeth configured along the inner wall of said second ring; a winding-up member having a second shaft erected vertically through said top member and into said second space; and an active gear mounted on a first shaft erected vertically from the bottom of said bottom member inside said first space, said active gear having upper teeth and lower teeth around the circumference, said upper teeth engaging said gear teeth of said second ring, said lower teeth engaging a passive gear which in turn winds up said winding-up member; wherein, when said first ring is turned, said second ring is turned as well due to magnetic attraction from said first ring; said second ring in turn drives said active and passive gears to wind up said winding-up member.
