This is an interesting idea we haven't come across before. Lewis Crathern is auctioning a piece of the kite he used to jump Worthing Pier with Jake Scrace back in 2009. It's all in a good cause, for charity as part of the Armada downwinder that is happening very soon.
The auction is on Ebay at http://www.ebay.com/itm/A-Piece-Of-Lewis-Cratherns-Worthing-Pier-Jump-Kite-/221278693211
Check out the event here
It looks like it could be going ahead on 14/15th September
