Tilda

Tilda are rightly obsessive about their product. So:

In a one kilo bag of Tilda there are 50,000 grains of rice. Each will be presented through the pages of the Evening Standard.

Each of the 50,000 grains will be auctioned with individual authentication certificates.
All money raised will go to charities.

The public vote on an online shortlist, choosing which life-size grain they want to be featured on Trafalgar Square’s fourth plinth.
