DIY lifesaver vests made of drink bottles

The Coast Guard office in Takamatsu, in Kagawa Prefecture is deploying these DIY lifesavers made from used plastic bottles. It's a cost-saving scheme: while new lifesavers cost up to $200 if purchased, these only cost $2 to make. The flotation device apparently works just as well. The idea came after a bunch of middle school kids on a field trip saved somebody's life by throwing him a raft made of 16 plastic bottles.
