Self-pouring polymer | Tubeless siphon demonstration

Demonstrate polymers’ unusual properties with a self-siphoning, cuttable liquid. Use a high molecular weight poly(ethylene glycol), also known as polyox, solution to amaze 11-16 learners when teaching polymers, their applications and properties, such as viscoelasticity.
Although chemistry textbooks typically depict substances as consisting of particles that are spherical in shape, the reality is somewhat more complicated. From proteins to plastics, we can better explain the properties of many materials that we encounter every day in terms of particles resembling chains of beads. Use this model to explain the tubeless siphon and why you can cut this non-Newtonian fluid.
