This medium cache is a typical lunch box. It is hidden near one of the top science department in the world, The Cavendish Laboratory. Many discoveries have been made here, such as DNA, Neutron and Electron. The laboratory has seen the most famous physicists in the world such as Sir Isaac Newton, Ernest Rutherford, Charles Wilson, Clerk Maxwell and JJ THOMPSON. JJ Thompson discovered the electron and thus ushered in what became known as modern physics. I have a personal connection to the site as many family members of mine have worked here and have dedicated their working lives to the laboratory and the progress of science.
