These amazing displays are provided free by the hotels.
The fountains of the Bellagio Hotel:
The display is free and shown regularly daily from the afternoon right through the evening until midnight. The set for the Bellagio fountain display is an 8.5 acre lake in front of the Bellagio. It is illuminated at night by 5,000 lights. The fountain players are 798 minishooters, 208 swaying oarsmen, 192 supershooters, and 16 extreme shooters capable of projecting water nearly 500 feet in the air; each fountain player is programmed. A fog system also helps the designers create moods for the displays. There are more than 30 songs which play on rotation with work ongoing to choreograph more songs.
WET Design is a world famous water design company responsible for the Bellagio Fountains, the Volcano at the Mirage and also the water features at the Aria Hotel.
The volcano of the Mirage Hotel:
The Mirage Volcano display is shown hourly every evening and is the only display on the Strip which combines fire with music and choreography. The set had a $25 million redesign in 2008 and includes 2 volcano systems, a lagoon and fire shooters that shoot flame on demand. These massive fireballs are capable of shooting more than 12 feet in the air. It also features waterfalls with surrounding pools including fire and smoke effects. The display has a hypnotic music score which was created exclusively for the volcano display by Mickey Hart, Grateful Dead drummer, and Zakir Hussain. The soundtrack incorporates chants, percussion and other tribal elements in an effort to reproduce the spirit of a volcano. In addition to the music score, the volcano’s sound recordings come from actual volcanoes.
