A helicopter bucket or helibucket is a specialized bucket suspended on a cable carried by a helicopter to deliver water for aerial firefighting. The design of the buckets allows the helicopter to hover over a water source—such as a lake , river , pond , or tank —and lower the bucket into the water to refill it.
In the 19th century, luminiferous aether (or ether), meaning light-bearing aether, was a theorized medium for the propagation of light. James Clerk Maxwell developed a model to explain electric and magnetic phenomena using the aether, a model that led to what are now called Maxwell's equations and the understanding that light is an ...
According to ancient and medieval science, aether (/ ˈ iː θ ər /, alternative spellings include æther, aither, and ether), also known as the fifth element or quintessence, is the material that fills the region of the universe beyond the terrestrial sphere. [1]

[10] Fire, earth, air, and water have become the most popular set of classical elements in modern interpretations.
Inside an ebb-and-flow hydroponic system employing individual buckets connected by fill/drain hoses. The earliest published work on growing terrestrial plants without soil was the 1627 book Sylva Sylvarum or 'A Natural History' by Francis Bacon, printed a year after his death. As a result of his work, water culture became a popular research ...
The highly anticipated movie "Alien: Romulus" is hitting theaters this week, and fans are eagerly searching for ways to win a movie-themed popcorn bucket.. Since the bucket is likely to sell out ...
Deep water culture (DWC) is a hydroponic method of plant production by means of suspending the plant roots in a solution of nutrient-rich, oxygenated water. Also known as deep flow technique (DFT), floating raft technology (FRT), or raceway, this method uses a rectangular tank less than one foot deep filled with a nutrient-rich solution with ...
