Sony sell Walkman inside a bottle of water
Sony's Walkman MP3 player is a pretty robust piece of kit, but this year, they launched a waterproof version for swimmers. In a bid to catch people's eye, they decided to market it - confidently - submerged inside a bottle of water.
That's a bit mental, but clearly a smart piece of advertising. Have a look at the video below. Might be useful if you want to listen to some sad trombone music in a flooded area.
