In the present experimental study, we investigate the transition in the debonding mechanism when going from a viscous liquid to a soft elastic solid using a probe tack geometry. We have developed a model system consisting of PDMS with different degrees of crosslinking, ensuring a continuous transition between the material classes. During debonding, a fingering instability with characteristic wavelength evolves. We explain the subsequent coarsening of the pattern for a Newtonian oil by linear stability analysis and identify the influence on the adhesion energy. Over a wide range of properties from liquid to solid, we present a quantitative description of the initially destabilizing wavelength for the observed interfacial and bulk mechanisms....
