This model of Stonehenge is one of eight other Jaffa Cake creations Dominic Wilcox made to represent Britain, from Tower Bridge to the Loch Ness monster. The building blocks were made by excavating about five different Jaffa Cakes then carefully balancing them in a circle. He created the strangely realistic reflection on the plate by shining a light through the orange cellophane packet.
