We demonstrate for the first time a rotational Meissner effect for liquid helium, analogous to the magnetic Meissner effect in superconductors. Liquid helium in a rotating cylinder is cooled through the lambda temperature. At sufficiently slow rotational speeds, the superfluid forms in a state of 0 total angular momentum, causing the container to rotate faster.
