A laminar flow is characterized by fluid particles following smooth paths in layers, with each layer moving smoothly past the adjacent layers with little or no mixing

Rubber bands stretched produce heat and when released, they absorb heat. It's all about an entropy change

Weissenberg effect: A non-Newtonian liquid can climb up a spinning rod due to polymer chains wrapping around the rod as it rotates

FUN FACT:

The Pitch Drop Experiment started in 1930 is the longest running lab experiment. It measures the flow of a piece of a highly viscous liquid, pitch. Pitch flows at a very low rate, taking several years to form a single drop. To date, only nine drops have fallen.

Photoelasticity and strain gages are complementary stress analysis tools. #strainblog. #strain_gages. #photostress.

If you put some soap or ink on a leaf, you obtain a ink propelled boat, using the Marangoni effect. The ink or the detergent has a lower surface tension than water and its flow provides thrust to push the boat forward https://t.co/Ji4riaLPq0 [gif: https://t.co/yDioEbBqKg]

Non-Newtonian fluids turn into solids when pressure is applied. It's called the process of impact-activated solidification that occurs when compressive forces are applied to fluid-grain suspensions [source and full video: https://t.co/nSZ2aFmmMQ]

[Harris Lab @FluidDanamics]

Surfers can interact through their mutual wavefield, forming a myriad of bound states. Without waves, such pairs collapse under the "Cheerios" effect.
