  First conceived as a topological construction, Wada basins abound in
dynamical systems. Basins of attraction showing the Wada property possess the
particular feature that any small perturbation of an initial condition lying on
the boundary can lead the system to any of its possible outcomes. The
saddle-straddle method, described here, is a new method to identify the Wada
property in a dynamical system based on the computation of its chaotic saddle
in the fractalized phase space. It consists of finding the chaotic saddle
embedded in the boundary between the basin of one attractor and the remaining
basins of attraction by using the saddle-straddle algorithm. The simple
observation that the chaotic saddle is the same for all the combinations of
basins is sufficient to prove that the boundary has the Wada property.
