Pressurized gas enters the housing and is directed through an orifice in a housing shelf upward into the lid. Starter plastic is placed on the shelf. A mold is held in the lid and the plastic assumes the shape of the mold as it is blown upward through the orifice into the lid. The lid has a central opening to allow the students to see the process of blow forming of plastics as it occurs. The device has a carrying handle, flanges to fasten it to a work surface, and locking toggle handles to assure a tight seal of lid and housing.
