Worlds Smallest Tesla Valve? - Shrinky Dink (Shrink Film) Microfluidics

Microfluidics is the study and construction of collections of tiny fluid channels that can accomplish an incredible array of tasks; from simple mixing, to math and computer logic. But making the flow cells that make use of the principles of microfluidics is normally expensive due to material and equipment costs.

In this video we explore a dirt cheap method for making very high quality microfluidic low cells, including one of the worlds smallest tesla valves, and a device meant to isolate cancer cells from a blood sample.
