China's Nuclear-Blast Resistant Floating Island
China is making a big, strong floating island that can survive nuclear blasts.
It's like a big boat that can stay at sea for a long time, even in rough weather.
Scientists will use it to do research in the ocean.
Some people might be worried because it could be used in places where countries are arguing about who owns the water.
China is building a floating artificial island designed to withstand nuclear blasts
The island, named Deep-Sea All-Weather Resident Floating Research Facility, is a 78,000-tonne, semi-submersible twin-hull platform
It can support 238 people for four months without needing new supplies and can operate far from home
The island uses a rare nuclear-blast-resistant design with 'metamaterial' sandwich panels
It is planned for deployment in wider ocean regions, including contested waters
