A vortex technique capable of calculating the Rayleigh--Taylor instability to large amplitudes in inviscid, incompressible, layered flows is introduced. The results show the formation of a steady-state bubble at large times, whose velocity is in agreement with the theory of Birkhoff and Carter. It is shown that the spike acceleration can exceed free fall, as suggested recently by Menikoff and Zemach. Results are also presented for instability at various Atwood ratios and for fluids having several layers.
