Rescue Worker Hops Quickly Around on Quicksand to Make It Ripple and Bounce

Staff of the Bay Search & Rescue captured fascinating footage in 2009 of the surreal rippling effect of walking on quicksand at Morcambe Bay in northwest England. The worker hops around quickly on the well-saturated sand to avoid becoming stuck and the quicksand, being a shear thinning non-Newtonian fluid, ripples and bounces with his movements.

Morecambe Bay in the UK is notorious for its quicksand. Bay Search and Rescue specialise in extracting people, animals and vehicles trapped in quicksand.
