Abstract:

Apparatus for generating the appearance of clouds by forcing air over dry ice and channeling the resultant cloud out the top of an enclosure. The apparatus includes an insert having four sides, a bottom and an open top. A manifold may be coupled to a perforation in the insert wherein an optional silo may extends from the manifold toward the open top of the insert. The manifold and silo may be adapted to store dry ice, or dry ice may be stored in a chamber juxtaposed to the manifold. A fan juxtaposed to manifold forces air into the manifold and, ultimately, over the dry ice. The resultant cloud is then channeled out of the manifold by a diffuser plate and, ultimately, out of the enclosure. In one embodiment, feet beneath the manifold provide a gap between the enclosure and the apparatus such that the cloud exits the enclosure.
