"Tell the chef, the beer is on me."
Non-Newtonian fluids are capable of all kinds of counter-intuitive behaviors. The animations above demonstrate one of them: the tubeless or open siphon. Once the effect is triggered by removing some of the liquid, the fluid quickly pours itself out of the beaker. This is possible thanks to the polymers in the liquid. The falling liquid pulls on the fluid left behind in the beaker, which stretches the polymers in the fluid. When stretched, the polymers provide internal tension that opposes the extensional force being applied. This keeps the fluid in the beaker from simply detaching from the falling liquid. Instead, it flows up and over the side against the force of gravity, behaving rather more like a chain than a fluid! (Image credit: Ewoldt Research Group, source)

"I'd love to help kickstart continued development! And 0 EUR/month really does make fiscal sense too... maybe I'll even get a shirt?" (there will be limited edition shirts for two and other goodies for each supporter as soon as we sold the 200)
