We investigate interactions and reconnections of quantum vortices in a four-dimensional superfluid, where vortices are surfaces rather than lines. Numerical simulations reveal stable intersecting surfaces that do not reconnect and reconnections with little energy dissipation, potentially indicating quasireversible dynamics. These behaviours extend the familiar three-dimensional picture and motivate studies of vortex dynamics and turbulence in higher dimensions.
