ABSTRACT:
An article for producing an interesting visual effect is disclosed. The article has a translucent or transparent conduit extending in a loop defining a path of fluid flow. A portion of the loop is contained in an opaque container and a portion extends out of the container. A pump moves a stream of liquid containing phosporescent particles through the conduit. A light in the container charges the particles immediately prior to their movement through the portion of the conduit outside the container where the glow from the moving particles are observable through the conduit wall. Continued operation continuously moves the particles past the light for recharging.
