We present a Smoothed Particle Hydrodynamics (SPH) simulation of a ball levitating in an air stream. We conducted experiments with various SPH techniques, such as Predictive-Corrective Incompressible SPH (PCISPH), Implicit Incompressible SPH (IISPH) and Divergence-Free SPH (DFSPH). However, the ball always escaped the air stream and fell onto the simulation floor. Therefore, we introduce a new heuristic to compute the Coandă effect that was shown to be missing in recent SPH works. Our method does not produce tensile and pairing instabilities typically found when negative pressure is involved. Since our method adds another external force to the Navier-Stokes equations, it can be generalized to any SPH-based method.
