Cavendish Laboratory : Lawrence Bragg's bubble raft
Cavendish Laboratory
<p style='text-align: justify;'>During the Second World War, Bragg invented the bubble raft in order to visualise the behaviour of dislocations in solids and their plastic deformation in two dimensions. Dislocations in the regular 'lattice' of soap bubbles are clearly demonstrated. The investigators were Bragg, J.F. Nye and W. Louier.</p>
