airbag trunks / self-rescue tool

In the countryside of China, without regular swimming pool, some children swim in the natural lakes and rivers where the safety facilities are not available. Without any protection, every year thousands of children die of drowning and the figure is getting worse . Although those kids are confident about their swimming skill, the outdoors environment involves many unexpectable factors which may cause dangers, for example ,the rushing torrent and the sudden leg cramps. With limited knowledge in self-rescue, children can’t save themselves in an emergency. So we put forward the airbag trunks concept, just like swimming with an “invisible buoy”.
