ABSTRACT:
An apparatus for generating static-like noise comprises a gun shaped plastic housing in which a drive roller and a driven roller are rotatably mounted in rolling engagement with each other. One of the rollers is covered with that portion of a Velcro material comprised of a plurality of flexible hooks while the other roller is covered with that portion of a Velcro material comprising a plurality of flexible loops. Motor means are provided and disposed within the housing for selectively causing the rollers to rotate. In this manner, the Velcro connecting elements continuously engage and disengage. The disengagement of the members produces the desired static-like noise.
