The effect is observed in small objects which are supported by the surface of a liquid. There are two types of such objects: objects which are sufficiently buoyant that they will always float on the surface (for example, Cheerios in milk), and objects which are heavy enough to sink when immersed, but not so heavy as to overcome the surface tension of the liquid (for example, steel pins on water).
Harvesting of cork from the forests of Algeria, 1930. Cork is a natural material used by humans for over 5,000 years. It is a material whose applications have been known since antiquity, especially in floating devices and as stopper for beverages, mainly wine, whose market, from the early twentieth century, had a massive expansion, particularly due to the development of several cork-based ...

Furthermore, 43% of retirees believe their benefits will be cut in the future, while 47% of nonretired adults worry that Social Security won't be able to pay them a benefit at all once they retire.
The Toniebox has been selling like mad this year. It's an audio player for kids that can play stories, podcasts, and songs. Each box comes with a character — a "Tonie" — whose audio matches ...
For a floating object, only the submerged volume displaces water. For a sunken object, the entire volume displaces water, and there will be an additional force of reaction from the solid floor. In order for Archimedes' principle to be used alone, the object in question must be in equilibrium (the sum of the forces on the object must be zero ...
We've rounded up 22 gifts that celebrate this beautifully unbalanced relationship where humans willingly become servants to creatures who occasionally knock water glasses off tables for fun.
