Bubble Raft Model - part 1

A short film demonstrating the creation of a bubble raft and highlighting that on manipulation that dislocations in the structure can be formed and repaired, similar to the close-packing seen in crystal structures. This silent film is likely to be an excerpt from a longer film on bubble rafts, possibly made in the 1940s by William Lawrence Bragg.
