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
Meniscus (liquid) the meniscus. This means that any instrument is calibrated for a specific liquid, usually water. Menisci are a manifestation of capillary action, by which surface adhesion pulls a liquid up to form a concave meniscus or internal cohesion pulls the liquid down to form a convex meniscus. This phenomenon is important in transpirational pull in plants. When a tube of a narrow bore, often called a capillary tube, is dipped into a liquid and the liquid wets the tube (with zero contact angle), the liquid surface inside the tube forms a concave meniscus, which is a virtually spherical surface having
