  Core collapse supernovae are dominated by weakly interacting neutrinos. This
provides a unique opportunity for macroscopic parity violation. We speculate
that parity violation in a strong magnetic field can lead to an asymmetry in
the explosion and a recoil of the newly formed neutron star. We estimate the
asymmetry from neutrino-polarized-neutron elastic scattering, polarized
electron capture and neutrino-nucleus elastic scattering in a (partially)
polarized electron gas.
