Abstract
A toy top comprises a base plate having a plurality of apertures therein, a rotatable disk which is mounted beneath the base plate, a plurality of balls which are received on the base plate and a transparent dome enclosing the balls and the base plate. The device is operative by depressing a central plunger to rotate the disk beneath the base plate. The rotatable disk has a plurality of projections thereon which pass beneath the apertures in the base plate so that they engage any of the balls received in the apertures to bump or pop the balls out of the apertures as the disk is rotated.
