We propose several experiments to test the non-abelian nature of quasi-particles in the fractional quantum Hall state of $\nu=5/2$. One set of experiments studies interference contribution to back-scattering of current, and is a simplified version of an experiment suggested recently by Das Sarma et al. A second set looks at thermodynamic properties of a closed system. A third set looks at electronic transport in an array of immobile quesi-particles. The first two sets are only weakly sensitive to disorder-induced distribution of localized quasi-particles.
