The two soothingly moving art installations, measuring 9.8 metres by 4 metres, are made of 1,216 bronze droplets, each weighing 180 grams. They are actually made of lightweight aluminium, coated with polished copper, and are hollow inside.
Each of the two installations can take 16 different shapes, including abstract art forms as well as forms you can recognize in the world around you. Fittingly, you can see the kinetic raindrops form things that can fly, such as an aeroplane, a hot air balloon, a kite and even a dragon. The maximum distance from the ceiling to the lowest point of the art form is said to be 7.3 meters.
According to Changi Airport, the Kinetic Rain installation is "the biggest and most complex kinetic sculpture of its kind in the world", and "synonymous with Singapore's garden city reputation where rain is a common feature in the tropical climate."
