Abstract
A SOLUTION of 75 per cent aqueous glycerol shows considerable viscosity (six times that of water) but no structure, so that small bubbles rise to the surface slowly but at a rate predictable from Stokes's law. A 0.07 per cent solution of agar, on the other hand, is only about 4 per cent more viscous than water; but eddies in it are destroyed as rapidly as in the glycerol. Air bubbles rise to the surface in characteristic jerks, and if small enough become trapped. Clearly a certain critical stress has to be exceeded in order to break the molecular framework.
