We numerically investigate the transition of the static quark-antiquark string into a static-light meson-antimeson system. Improving noise reduction techniques, we are able to resolve the signature of string breaking dynamics for nf=2 lattice QCD at zero temperature. We discuss the lattice techniques used and present results on energy levels and mixing angle of the static two-state system. The string breaking is 0, by means of an animation of the action density distribution as a function of the static colour source-antisource separation. This results can be related to properties of quarkonium systems.
