This is called a "water triangle": The water triangle is rotated until it shows a measurement of 4 units on the left side and 6 units on the right side. Suppose the triangle is tilted even more until the water level on the right side is at 8 units. Predict what the water level in units will be on the left side. Typical Solutions
Bridgewater Triangle. The Bridgewater Triangle is an area of about 200 square miles (520 km 2) within southeastern Massachusetts in the United States, [1] claimed to be a site of alleged paranormal phenomena, ranging from UFOs to poltergeists, and other spectral phenomena, various bigfoot -like sightings, giant snakes [2] and thunderbirds.

The Tetractys symbolizes the four classical elements—air, fire, water, and earth. The Tetractys represented the organization of space: the first row represented zero dimensions (a point) the second row represented one dimension (a line of two points) the third row represented two dimensions (a plane defined by a triangle of three points)
The Penrose triangle, also known as the Penrose tribar, the impossible tribar, [1] or the impossible triangle, [2] is a triangular impossible object, an optical illusion consisting of an object which can be depicted in a perspective drawing. It cannot exist as a solid object in ordinary three-dimensional Euclidean space, although its surface ...
38 cm × 30 cm (15 in × 12 in) Waterfall (Dutch: Waterval) is a lithograph by the Dutch artist M. C. Escher, first printed in October 1961. It shows a perpetual motion machine where water from the base of a waterfall appears to run downhill along the water path before reaching the top of the waterfall. While most two-dimensional artists use ...
The phase diagram shows, in pressure–temperature space, the lines of equilibrium or phase boundaries between the three phases of solid, liquid, and gas. The curves on the phase diagram show the points where the free energy (and other derived properties) becomes non-analytic: their derivatives with respect to the coordinates (temperature and ...
The solid green line applies to most substances; the dashed green line gives the anomalous behavior of water. In thermodynamics, the triple point of a substance is the temperature and pressure at which the three phases (gas, liquid, and solid) of that substance coexist in thermodynamic equilibrium. [ 1 ] It is that temperature and pressure at ...
The classical elements typically refer to earth, water, air, fire, and (later) aether which were proposed to explain the nature and complexity of all matter in terms of simpler substances. [1][2] Ancient cultures in Greece, Angola, Tibet, India, and Mali had similar lists which sometimes referred, in local languages, to "air" as "wind", and to ...
