Someone on the guardian comments works out the bars must be 12g of gold each, that is pretty small. 1 tablespoon of sugar is about that weight, and gold is pretty dense, surely these will be about the size of a staple.
This stunt is part of Folkestone Triennial.
UPDATE: Guardian are live blogging it.
This is my website The Folkestone Gerald that I built in a fury of enthusiasm when I first came to Folkestone in approximately '04. I'd been a frequent visitor for a while before that so I am technically one of those Down From Londons you get now. The site was a lot more dynamic with a gig calendar and voting for favourite places and stuff, and I know it was a useful resource for those who were thinking of moving here. Now I've moved out of Folkestone again (though only to Hythe) it doesn't get as much attention as it used to. Ironic really as The town is now becoming the exciting place we knew it was just about to. I am not Gerald by the way, this comes from a pretend paper in an episode of Brasseye or something, the Portsmouth Gerald, and how there is a local paper here called the Folkestone Herald. Puns like this are great aren't they? Do get in touch if you have anything to offer, email anythign @ this domain, or try @folkestone or @pauly on Twitter.
