The Whistle is a simple glow-in-the-dark blowing implement that survivors buried under rubble can use to attract attention. The compact size and ball-shape make them easy to roll into the rubble area and thanks to their glow, they can be easily located. I suppose the rescue team has to throw in a handful, in the hope that someone catches one and blows the whistle.
Whistle is a 2013 IDEA Awards entry.
