What is the blue one for?

The blue band was launched by BBC Radio One as part of their One Life campaign to tackle bullying.

The blue band is stamped with 'Beat Bullying' and has been worn by loads of celebrities and sports stars including footballers Frank Lampard and Rio Ferdinand and guitar band Rooster.

The bands were given away free, but have been so popular that Radio One has been unable to send bands to everyone who has requested one.
