We will present novel experiments in brittle gels, probing the dynamics of crack fronts as the fronts become unstable. By comparing the surface area created by unstable cracks to local velocity and curvature of the propagating crack fronts that created the fracture surface, we test the validity of planar front perturbation theory to bulk 3D fracture.
