The coiling instability of a liquid 'rope' falling on a solid surface was presented. The study suggests that coiling could occur in three different regimes - viscous, gravitational and inertial, depending on the fluid viscosity and density. The study shows that all the results could be rescaled in a universal way that allows to predict the frequency of coiling of honey on toast. It was also observed that, as the fall height increases, the coiling frequency decreases and subsequently increases again, and give oscillation between two coiling states with different frequencies in the gravitational-to inertial transitional range.
