Abstract
A thin, planar crack, inside a swollen gel is initially filled with ai r, and then exposed to a bas solvent S, under a given pressure head p0 . The gel shrinks and the crack opens up. We predict a well defined pr opagation speed for the tip of the opened region, proportional to p0(1 /2). For p0 = 1 atm we expect c approximately 10 cm/s.
