what is e4 estings?

We have been asked to create a e4 estings for our next project but what is it?

From the e4 website:
Every year we challenge you to do something rather special by making an on-air sting for E4. And 2011 is no different.
The 2011 competition is now open. Enter the 2011 E stings competition here
The 1st Prize winner will receive a £2500 and a runner up will receive £500.
The finalists will also be invited to attend an awards ceremony in glamorous London where the final winner will be announced. Special!

E4 estings is a competition run by the channel E4, its where the public can send in their wierdest, wackiest videos to be shown on E4 inbetween programmes in the ad break. The video has to be 10 seconds long and include the e4 logo and music that they have supplied.
