Abstract
A spark producing mechanism for a toy includes an at least partially transparent housing, a rotatable abrasive element in the housing and a motor for rotating the abrasive element. The mechanism further includes at least one flint element which is loosely captured in the housing so that it can contact and carom off the abrasive element to randomly produce sparks in the housing during rotation of the abrasive element.
