The Finnish invention, Fogscreen® has continued its success across the globe, displaying at amusement parks, museums, aquariums, fairs, night clubs and restaurants.

A thin curtain of 'dry' fog, images can be projected directly on to it, giving the impression that they are floating in the air.

The fog itself is made with ultrasonic waves and ordinary tap water, so no chemicals are needed, and is said to feel dry and cool when touched.

The 'screen' can be either translucent or fully opaque and works in both natural light and in darkened rooms.

Millions of people have already walked through the FogScreen projection screen and has been seen at Disney World, Ripley's Believe it or Not and Eurovision to name a few.
