Capillary rise or fall in a tube. Jurin's law , or capillary rise , is the simplest analysis of capillary action —the induced motion of liquids in small channels [ 1 ] —and states that the maximum height of a liquid in a capillary tube is inversely proportional to the tube's diameter .
The experiment uses a simple barometer to measure the pressure of air, filling it with mercury up until 75% of the tube. Any air bubbles in the tube must be removed by inverting several times. After that, a clean mercury is filled once again until the tube is completely full. The barometer is then placed inverted on the dish full of mercury.
It consists of a segmented tube, usually of bamboo, pivoted to one side of its balance point. At rest, its heavier end is down and resting against a rock. A trickle of water into the upper end of the tube accumulates and eventually moves the tube's centre of gravity past the pivot, causing the tube to rotate and dump out the water. The heavier ...

Tubing, also known as inner tubing, bumper tubing, towed tubing, biscuiting (in New Zealand), or kite tubing, is a recreational activity where an individual rides on top of an inner tube, either on water, snow, or through the air. The tubes themselves are also known as "donuts" or "biscuits" due to their shape.
Submerged floating tunnels can be anchored to the seafloor (left) or suspended from a pontoon (right) A submerged floating tunnel (SFT), also known as submerged floating tube bridge (SFTB), suspended tunnel, or Archimedes bridge, is a proposed design for a tunnel that floats in water, supported by its buoyancy (specifically, by employing the hydrostatic thrust, or Archimedes' principle).
An asteroid nearly the size of a football field now has a greater than one percent chance of hitting Earth in about eight years. Such an impact has the potential for city-level devastation ...
Block: Water descends from a relatively wide stream or river. [1] [2] Cascade: Water descends a series of rock steps. [1] [2] Segmented: Distinctly separate flows of water form as it descends. [1] Tiered: Water drops in a series of distinct steps or falls. [1] Punchbowl: Water descends in a constricted form and then spreads out in a wider pool. [1]
