Glaciator Effects at Olympic Legacy Theatre

August 18, 2004

Utah’s Salt Lake City Olympic Legacy Theatre uses a pair of Jem Glaciator heavy foggers to create a special cloud effect during the opening and closing scenes of a feature movie that is presented several times each day.

Supplied by Las Vegas-based atmospheric and effects specialists Water FX, the Glaciators are used to create a three-dimensional cloud at the beginning of the film, a curved 37’ fog barrier that covers the projection screen. The fog creates a curtain onto which three projectors cast images of blue clouds. The fog curtain is controlled via fans and manifolds, and at one point a hole is blown through the cloud to create the effect for viewers of flying through the clouds. The fog is then diverted and rolls across the floor at the public’s feet.

At the end of the movie, viewers journey back through the clouds. Some 150 feet of ducting, plus 120 feet of manifold and 100 feet of tubing with a large diverter box are used to channel the effect. The fog effect is designed to operate every 20 minutes for 12 hours a day.

Effects Designer Tim Vanwormer of Water FX states that not only have the Glaciators held up great, they have saved money on alternative systems as well as a lot of trouble. “Handling is easier with the Glaciators than with dewar vessels and CO2 would have been hard to handle,” he states. “Also, CO2 takes oxygen out of the air and they would have had to install a complete oxygen subsystem and oxygen monitoring devices to make sure they weren’t endangering the people in the theatre. They are saving money on the front and backside of the installation – both the installation side and the operational side.”

Designed for ultimate ease, all that is needed to run the Jem Glaciators is power and heavy fog fluid. “It was a matter of plugging them in and positioning the diverters,” Tim says. “Other advantages are the duty cycle and the output volume.”

Water FX may have another Glaciator install on the horizon, and a unique one at that. They are hoping to put a Glaciator into the bathroom of a club bar, creating a smoke curtain divider wall between the men’s and women’s restrooms.
