A self-lightening oval shaped life jacket enables lifesavers to perform rescue operations more easily and practically. The specific oval shape fits your palm and the life jacket can be thus threw to the Drowning more accurately and further. Ball 911 is also equipped with light guiding thin film, which directs the large area solar energy into small solar cells, and a Lithium thin film battery within it. This allows the life jacket to shine during nighttime, indicating the position of the drifter. The survival probability and rescue rate can be greatly enhanced by simply putting this life jacket on. The buoyancy of this life jacket comes from the filling of CO2 gas. When the drifter receives Ball 911, the life jacket can be pumped by pulling the bolt out. Then the drifter just has to buckle himself up and wait for rescue.
