The collapse of a vapor bubble in a corner generates a jet whose direction depends on the corner opening angle and bubble position. Experimental data is found to agree well with a potential flow model that gives analytical solutions for a family of corner opening angles.

This movie shows an example of a laser-induced bubble, recorded at 100,000 frames per second. The bubble is about 2 mm in diameter at its maximum.
