The Rain Vortex
The Rain Vortex
The Rain Vortex, sponsored as the HSBC Rain Vortex, is the world's largest and tallest indoor waterfall, standing at 40 metres (130 ft) high.Recirculating rain water is pumped to the roof to free fall through a round hole at up to 37,850 liters (8,330 imp gal; 10,000 U.S. gal) per minute to a basement-level pool.An acrylic funnel at the bottom prevents splashing and insulates the sound of the cascade. The toroid-shaped roof has more than 9,000 pieces of glass spanning 200 by 150 meters (660 by 490 ft)with a sloped oculus as the mouth of the waterfall acting as "a continuation of the building...completed in a liquid form."At night, the circular walls of the waterfall becomes a 360-degree stage for a light-and-sound show.
To prevent excess humidity in the Jewel, the waterfall's flow alternates between cascades and trickles that reduce air turbulence. The design process by WET Design engineers included testing a one-fifth-scale model and a full-size partial prototype
The Changi Airport Skytrain connecting the terminals passes above ground near the waterfall, allowing passengers remaining airside to see the Vortex and Jewel itself.
Canopy Par
At the topmost level of Jewel, the 14,000 square metres (150,000 sq ft) Canopy Park houses recreation and leisure attractions.About half of the total landscaping is hosted at Canopy Park, including two gardens: Topiary Walk and Petal Garden.The Topiary Walk features animal-shaped topiaries at every corner, while the Petal Garden has seasonal floral displays. The park includes a suspension bridge called the Canopy Bridge that is located 23 metres (75 ft) above the ground which offers a panoramic view of the Rain Vortex. At 50 metres (160 ft) long, the Canopy Bridge also has a glass panel flooring at the centre section that offers a view through to level 1 of Jewel.
