We consider a random walk on S n-1 , the standard sphere of dimension n-1, generated by random rotations on randomly selected coordinate planes i, j with 1 ≤ i < j ≤ n. This dynamic was used by Marc Kac as a model for the spatially homogeneous Boltzmann equation. We prove that the spectral gap on S n-1 is n -1 up to a constant independent of n.
