Cavitation Tests: Nuclei Dissolving 



The film-forming materials selected were used to create monomolecular 

 surface films about nuclei. The nuclei were produced by cavitating saturated 

 water solutions, and the retardation of nuclei dissolving obtained by measuring 

 the tensile strength that ensued 30 minutes later. The data spread between the 

 extremes of no dissolving and the rapid dissolving of the distilled water used to
