Coconut water pulp ("meat"). In young coconuts, the liquid and air may be under some pressure and may spray slightly when the inner husk is first penetrated. Coconuts that have fallen to the ground are susceptible to rot and damage from insects or other animals. Plain coconut water has long been a popular drink in tropical countries, where it is available fresh, canned, or bottled. Coconuts for drinking are served chilled, fresh, or packaged. They are often sold by street vendors who cut them open with machetes or similar implements in front of customers. Coconut water for retail can be found in
Liquid-crystal display This effect is based on an electro-hydrodynamic instability forming what are now called "Williams domains" inside the liquid crystal. In 1964, George H. Heilmeier, then working at the RCA laboratories on the effect discovered by Williams achieved the switching of colors by field-induced realignment of dichroic dyes in a homeotropically oriented liquid crystal. Practical problems with this new electro-optical effect made Heilmeier continue to work on scattering effects in liquid crystals and finally the achievement of the first operational liquid-crystal display based on what he called the "dynamic scattering mode" (DSM). Application of a voltage to a DSM display switches
