  We study chaotic motion of classical closed strings in the five-dimensional
Anti-de Sitter (AdS) soliton spacetime. We first revisit classical chaos using
a cohomogeneity-1 string ansatz. We then consider turbulent behaviors of the
classical strings when the spatial dependence of the string world-sheet is
included. Sensitivity to initial conditions in chaotic systems suggests that
the string under chaos tends to stretch in the AdS soliton spacetime in a
Lyapunov timescale. In this process, the orbital angular momentum transfers to
internal spin due to the turbulence on the string. It follows that the string
stays around the tip of the AdS soliton with a jumbled profile. We evaluate the
spectra of conserved quantities and discuss their universal power-law scalings
in the turbulent behaviors.
