We propose the generation of 3D linear light bullets propagating in free space using a single passive optical surface. The device is a single-layer photonic crystal slab. It can automatically transform an incident conventional Gaussian pulse into a light bullet in the reflection. Our approach also provides simultaneous control of various properties including group velocity, spin, and orbital angular momentum. Our results may advance practical applications of light bullet.
