  1. ωC denotes the critical cut-off frequency between the synchronous and asynchronous regimes for the data in Fig. 4b. η0 is the static viscosity derived from equation (1), is the angle by which the wire returns back at high frequency and G is the elastic modulus obtained from equation (4). The error bars are defined as s.e.m.
