A life ring is only effective when it can be reached by a struggling swimmer, which is what makes the Life Rescue such an intelligent invention. This device is deflated, compact and lightweight, embodying several features that make it quite easy to maneuver.
Siew Ming Cheng proposes the installation of a lifebuoy stand on popular beaches, each holding three inflatable tubes. Access them by pulling them out by the long handgrip; simply clutch this and release it to execute your launch.
When the Life Rescue lands in the water -- hopefully quite close to the victim -- a pill inside of it will dissolve. This causes the core to shift upwards and the lifesaver to expand and fill with air immediately.
