Beijing’s winter bubble. 2022 Winter Paralympics
The 2022 Winter Paralympics begins today in Beijing, as the Chinese capital becomes the first city to host both the summer and winter editions of the Paralympic Games. Over the next 10 days, about 600 athletes will compete in 78 different events across six sports: alpine skiing, cross-country skiing, biathlon, snowboarding, para ice hockey and wheelchair curling. All the events will take place in a strict Covid ‘bubble’ system to ensure a safe and successful Games.
Speaking of bubbles, today we’re looking at the National Aquatics Centre, a box-shaped building that will host the wheelchair-curling events. The design of the bubble-wrapped outside, made from a thin, transparent plastic material called ETFE, is based on the Weaire-Phelan geometric structure, which represents the natural pattern of bubbles in soap lather.
The venue was originally constructed to host the swimming, diving and synchronised swimming competitions at the 2008 Summer Olympics and Paralympics. But its pool has been turned into an ice rink for the winter events, making it the first sports arena in the world that can switch between water and ice.
