Supertrees light up the night sky in Singapore


The Supertree Grove is illuminated during the Gardens by the Bay, Light and Sound show on July 2 in Singapore.

The free nightly light and sound display illuminates 18 150-foot-tall "supertrees" adorned with 163,000 plants of more than 200 species of bromeliads, orchids, ferns, and tropical climbing flowers. The vertical forest is part of a multimillion-dollar project called Gardens by the Bay and opened to the public on June 29.

The trees are constructed of concrete and steel, but are fitted with planting panels to generate solar power, collect rainwater and cool surrounding buildings. Aerial walkways between some of the artificial trees provide tourists with spectacular views of Singapore's downtown district.
