Abstract
Abstract A sparking rollerskate includes a clam shell like shoe portion and a wheel assembly. The wheel assembly supports a plurality of rolling wheels together with an internal flint supporting mechanism. One of the skate wheels further includes an abrasive drum which receives the end portion of the flint to provide a spark producing action as the wheel is rotated. The wheel assembly and clam shell like shoe portion are configured to provide a captivating attachment of the wheel assembly to the shoe portion when the clam shell halves thereof are closed. The shoe portions define internal cavities which captivate the wearer's foot during the assembly process to facilitate attachment of the roller skate thereto.
