A volcano without the safety and security hazard of using fire and, flammable substances. Its all done, cleverly we think, with water, lighting and sound. Of course the water gets projected, foamed, misted and thoroughly agitated to perform under different lighting effects and all synchronised with the sound. We can programme shows to specific requirements, we have done one for theme restaurant where the owners did not want the diners be put of their food, but a typical sequence starts with very low rumbling just distinguishable to be disturbing. Animals indicate their foreboding with elephants trumpeting and tigers roaring, slowly the tension builds until the first eruption still surprises. Thereafter the display is spectacular until the final eruption ends the show. Elapsed time: 15 - 20minutes. Obviously this is not a full sized volcano but can be tailored to site requirements and requires local civil work.
