In theories with gauge mediated supersymmetry breaking, the scalar tau, (${\tilde \tau_1}$) is the lightest observable superpartner for part of the parameter space. At LEP 2, the production of such a $\tilde \tau_1$ pair and their subsequent decays give rise to a pair of $\tau$ leptons plus missing energy from the unobserved gravitinos. The angular distributions of the $\tau$'s are different from those arising from the production and decay of W pairs, and thus will constitute an interesting signal for supersymmetry. We also consider ${\tilde \tau_1}$ pair production in the complementary part of parameter space where the lightest neutralino is lighter than the $\tilde \tau_1$.
