Research is conducted on the aging of liquid foam by interbubble gas            diffusion.  This spontaneous phenomenon not only changes the bubble             sizes and reduces the available surface, but, with sufficient time,             leads to a reduction in the number of bubbles present and hence to              ultimate coalescence of the foam.  The experimental method employs two          novel techniques.  The first involves the very slow rotation of the             foam about a horizontal axis.  The second technique stops further aging         by means of the very rapid hardening of the foam with nongas-producing          polymerization and/or cross linkage.  The foam will be generated by             bubbling presaturated nitrogen through an appropriate liquid mixture.           After the resulting foam is aged and hardened, its volumetric gas               fraction, and bubble size and shape distributions will be measured              photomicrographically at sampling planes within the foam that will be           cut and polished for the purpose.
