Psi Wheel
A psi wheel is pyramid-shaped top-like device consisting of a small piece of paper or foil balanced on the tip of a pointed object (such as a toothpick or needle). It is commonly used in attempts to prove the validity of telekinesis, by rotating the wheel claiming to use the power of the mind alone. However, this "experiment" does not prove psychokinesis or other parapsychological phenomenon as hidden heat and wind sources can be used to turn it. Psychokinesis is not proven to date, while many laws of physics prohibit it as such, psychokinesis is pseudoscientific. History In the 1968 psychic powers film '' The Power'', a group of witnesses seated around a table watch a stunned telekinetic as a psi wheel turns by the application of telekinetic force by one of the characters. Construction There are several designs for the shape of the psi wheel, but the most common is an inverted funnel-shaped pyramid. This psi wheel shape may be constructed by creasing a small (around 2 in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pyramid
A pyramid (from el, πυραμίς ') is a structure whose outer surfaces are triangular and converge to a single step at the top, making the shape roughly a pyramid in the geometric sense. The base of a pyramid can be trilateral, quadrilateral, or of any polygon shape. As such, a pyramid has at least three outer triangular surfaces (at least four faces including the base). The square pyramid, with a square base and four triangular outer surfaces, is a common version. A pyramid's design, with the majority of the weight closer to the ground and with the pyramidion at the apex, means that less material higher up on the pyramid will be pushing down from above. This distribution of weight allowed early civilizations to create stable monumental structures. Civilizations in many parts of the world have built pyramids. The largest pyramid by volume is the Great Pyramid of Cholula, in the Mexican state of Puebla. For thousands of years, the largest structures on Earth were pyrami ...

Paper
Paper is a thin sheet material produced by mechanically or chemically processing cellulose fibres derived from wood, rags, grasses or other vegetable sources in water, draining the water through fine mesh leaving the fibre evenly distributed on the surface, followed by pressing and drying. Although paper was originally made in single sheets by hand, almost all is now made on large machines—some making reels 10 metres wide, running at 2,000 metres per minute and up to 600,000 tonnes a year. It is a versatile material with many uses, including printing, painting, graphics, signage, design, packaging, decorating, writing, and cleaning. It may also be used as filter paper, wallpaper, book endpaper, conservation paper, laminated worktops, toilet tissue, or currency and security paper, or in a number of industrial and construction processes. The papermaking process developed in east Asia, probably China, at least as early as 105 CE, by the Han court eunuch Cai Lun, although the ...

Aluminum Foil
Aluminium foil (or aluminum foil in North American English; often informally called tin foil) is aluminium prepared in thin metal leaves with a thickness less than ; thinner gauges down to are also commonly used. Standard household foil is typically thick, and heavy duty household foil is typically . The foil is pliable, and can be readily bent or wrapped around objects. Thin foils are fragile and are sometimes laminated with other materials such as plastics or paper to make them stronger and more useful. Annual production of aluminium foil was approximately in Europe and in the U.S."Foil & Packaging" . The Aluminum Association (USA). in 2003. Approximately 75% of aluminium foil is used for |
Telekinesis
Psychokinesis (from grc, ψυχή, , soul and grc, κίνησις, , movement, label=ㅤ), or telekinesis (from grc, τηλε, , far off and grc, κίνησις, , movement, label=ㅤ), is a hypothetical psychic ability allowing a person to influence a physical system without physical interaction. Psychokinesis experiments have historically been criticized for lack of proper scientific control, controls and repeatability. There is no good evidence that psychokinesis is a real phenomenon, and the topic is generally regarded as pseudoscience. Etymology The word ''psychokinesis'' was coined in 1914 by American author Henry Holt (publisher), Henry Holt in his book ''On the Cosmic Relations''. The term is a Compound (linguistics) , compound of the Greek language, Greek words ψυχή (''psyche'') – meaning "mind", "soul", "spirit", or "breath" – and κίνησις (''kinesis'') – meaning "motion" or "movement".

Pseudoscientific
Pseudoscience consists of statements, beliefs, or practices that claim to be both scientific and factual but are incompatible with the scientific method. Pseudoscience is often characterized by contradictory, exaggerated or unfalsifiable claims; reliance on confirmation bias rather than rigorous attempts at refutation; lack of openness to evaluation by other experts; absence of systematic practices when developing hypotheses; and continued adherence long after the pseudoscientific hypotheses have been experimentally discredited. The demarcation between science and pseudoscience has scientific, philosophical, and political implications. Philosophers debate the nature of science and the general criteria for drawing the line between scientific theories and pseudoscientific beliefs, but there is general agreement on examples such as ancient astronauts, climate change denial, dowsing, evolution denial, Holocaust denialism, astrology, alchemy, alternative medicine, occultism, uf ...

The Power (1968 Film)
''The Power'' is a 1968 American Tech noir, science fiction thriller film from MGM, produced by George Pal, directed by Byron Haskin (his final film), that stars George Hamilton and Suzanne Pleshette. It is based on the 1956 science fiction novel '' The Power'' by Frank M. Robinson. The storyline concerns a hunt to find a man who seems the ability to control or slay others with their minds. Plot The Committee on Human Endurance researches the human body's ability to survive pain and physical stress as part of the space program. Dr. Henry Hallson, an anthropologist on the committee, has designed a series of anonymous questionnaires to screen people with greater survival capacity, using other committee members as preliminary subjects. Hallson reveals his findings at a meeting with chairman and biologist Dr. Jim Tanner, geneticist Dr. Margery Lansing, physicist Dr. Carl Melnicker, biologist Dr. Talbot Scott, Dr. Norman Van Zandt, and government liaison Arthur Nordlund.

Thumbtack
A drawing pin (in British English) or thumb tack (in North American English) is a short nail or pin used to fasten items to a wall or board for display and intended to be inserted by hand, usually using the thumb. A variety of names is used to refer to different designs intended for various purposes. Thumb tacks made of brass, tin or iron may be referred to as brass tacks, brass pins, tin tacks or iron tacks, respectively. These terms are particularly used in the idiomatic expression ''to come'' (or ''get'') ''down to brass'' (or otherwise) ''tacks'', meaning to consider basic facts of a situation. History The drawing pin was invented in name and first mass-produced in what is now the United States in the mid/late 1750s. It was first mentioned in the Oxford English Dictionary in 1759. It was said that the use of the newly invented drawing pin to attach notices to school house doors was making significant contribution to the whittling away of their gothic doors. Modern draw ...

Eraser
An eraser (also known as a rubber in some Commonwealth countries, including South Africa from the material first used) is an article of stationery that is used for removing marks from paper or skin (e.g. parchment or vellum). Erasers have a rubbery consistency and come in a variety of shapes, sizes and colors. Some pencils have an eraser on one end. Less expensive erasers are made from synthetic rubber and synthetic soy-based gum, but more expensive or specialized erasers are made from vinyl, plastic, or gum-like materials. At first, erasers were invented to erase mistakes made with a pencil; later, more abrasive ink erasers were introduced. The term is also used for things that remove marks from chalkboards and whiteboards. History Before rubber erasers used today, tablets of wax were used to erase lead or charcoal marks from paper. Bits of rough stone such as sandstone or pumice were used to remove small errors from parchment or papyrus documents written in ink. Cr ...

Sponge
Sponges, the members of the phylum Porifera (; meaning 'pore bearer'), are a basal animal clade as a sister of the diploblasts. They are multicellular organisms that have bodies full of pores and channels allowing water to circulate through them, consisting of jelly-like mesohyl sandwiched between two thin layers of cells. Sponges have unspecialized cells that can transform into other types and that often migrate between the main cell layers and the mesohyl in the process. Sponges do not have nervous, digestive or circulatory systems. Instead, most rely on maintaining a constant water flow through their bodies to obtain food and oxygen and to remove wastes. Sponges were first to branch off the evolutionary tree from the last common ancestor of all animals, making them the sister group of all other animals. Etymology The term ''sponge'' derives from the Ancient Greek word ( 'sponge'). Overview Sponges are similar to other animals in that they are multicellular, he ...

Bottle Cap
A bottle cap or bottle top is a closure for the top opening of a bottle. A cap is sometimes colourfully decorated with the logo of the brand of contents. Plastic caps are used for plastic bottles, while metal with plastic backing is used for glass; plastic caps are commonly made from PE or PP, whilst metal caps are usually either steel or aluminum. Plastic caps may have a pour spout. Flip-Top caps like Flapper closures provide controlled dispensing of dry products. Caps for plastic bottles are often made of a different type of plastic from the bottle. A cork is another type of closure for the top of a bottle. Types Caps were originally designed to be pressed over and around the top of a glass bottle to grab a small flange on the bottleneck. Crown cork The crown cork was patented by William Painter on February 2, 1892 (U.S. Patent 468,258). It had 24 teeth and a cork seal with a paper backing to prevent contact between the contents and the metal cap. The current versio ...
