Sandstone is a clastic sedimentary rock composed mainly of sand-sized mineral particles or rock fragments.
Monazite is a reddish-brown phosphate mineral containing rare-earth metals. To be more specific, it represents a group of minerals. The most common species of the group is monazite-(Ce), that is, the cerium-dominant member of the group. It occurs usually in small isolated crystals. It has a hardness of 5.0 to 5.5 on the Mohs scale of mineral hardness and is relatively dense, about 4.6 to 5.7 g/cm3. There are at least four different "kinds" (actually separate species) of monazite, depending on relative elemental composition of the mineral:
Coin magic is the manipulating of coins to entertain audiences. Because coins are small, most coin tricks are considered close-up magic or table magic, as the audience must be close to the performer to see the effects. Though stage conjurers generally do not use coin effects, coin magic is sometimes performed onstage using large coins. In a different type of performance setting, a close-up coin magician will use a large video projector so the audience can see the magic on a big screen. Coin magic is generally considered harder to master than other close-up techniques such as card magic, as it requires great skill and grace to perform convincingly, and this takes a lot of practice to acquire.
A trick deck usually refers to a deck of playing cards that has been altered in some way to allow magicians to perform certain card tricks where sleight of hand would be too difficult or impractical.
Petrography is a branch of petrology that focuses on detailed descriptions of rocks. Someone who studies petrography is called a petrographer. The mineral content and the textural relationships within the rock are described in detail. The classification of rocks is based on the information acquired during the petrographic analysis. Petrographic descriptions start with the field notes at the outcrop and include macroscopic description of hand specimens. However, the most important tool for the petrographer is the petrographic microscope. The detailed analysis of minerals by optical mineralogy in thin section and the micro-texture and structure are critical to understanding the origin of the rock. Electron microprobe analysis of individual grains as well as whole rock chemical analysis by atomic absorption, X-ray fluorescence, and laser-induced breakdown spectroscopy are used in a modern petrographic lab. Individual mineral grains from a rock sample may also be analyzed by X-ray diffraction when optical means are insufficient. Analysis of microscopic fluid inclusions within mineral grains with a heating stage on a petrographic microscope provides clues to the temperature and pressure conditions existent during the mineral formation.
Spoon bending is the apparent deformation of objects, especially metal cutlery, either without physical force, or with less force than would normally seem necessary. It is a common form of stage magic, and a variety of methods are used to produce the illusion.
Sand casting, also known as sand molded casting, is a metal casting process characterized by using sand as the mold material. The term "sand casting" can also refer to an object produced via the sand casting process. Sand castings are produced in specialized factories called foundries. Over 60% of all metal castings are produced via sand casting process.
Ching Ling Foo was the stage name of the Chinese magician Chee Ling Qua. He is credited with being the first modern East Asian magician to achieve world fame.
The Indian rope trick is a magic trick said to have been performed in and around India during the 19th century. Sometimes described as "the world’s greatest illusion", it reputedly involved a magician, a length of rope, and one or more boy assistants.
A thumb tip is a magician's prop designed to fit over and appear to be the magician's thumb used for vanishing, producing, or switching small objects. A classic effect is to have a silk handkerchief or other small object pressed into the top of the left fist. After pushing it well in with the right thumb, the left fist is opened to show the silk has disappeared. Alternatively, a lit cigarette, liquid, salt or other small objects can be made to disappear in a similar manner.
Wood finishing refers to the process of refining or protecting a wooden surface, especially in the production of furniture where typically it represents between 5 and 30% of manufacturing costs.
Magic sand or hydrophobic sand is a toy made from sand coated with a hydrophobic compound. The presence of this hydrophobic compound causes the grains of sand to adhere to one another and form cylinders when exposed to water. When the sand is removed from water, it is completely dry and free flowing. Magic sand is also known as Aqua Sand.
The Twenty-One Card Trick, also known as the 11th card trick or three column trick, is a simple card trick that uses basic mathematics to reveal the user's selected card.
Sikhye is a traditional sweet Korean rice beverage, usually served as a dessert. In addition to its liquid ingredients, Sikhye contains grains of cooked rice and in some cases pine nuts.
The Tarbell Course in Magic is a notable encyclopedia of magic amongst professional and amateur magicians. It has eight volumes; the first five were part of the original home-study correspondence course compiled in 1928 by Dr. Harlan Tarbell, the remaining three volumes being added on later.
A glass stirring rod, glass rod, stirring rod or stir rod is a piece of laboratory equipment used to mix chemicals. They are usually made of solid glass, about the thickness and slightly longer than a drinking straw, with rounded ends.
Sand is a granular material composed of finely divided rock and mineral particles. It is defined by size, being finer than gravel and coarser than silt. Sand can also refer to a textural class of soil or soil type; i.e., a soil containing more than 85 percent sand-sized particles by mass.
The Inexhaustible Bottle is a classic magic trick performed by stage magicians. It dates to the 17th century and has since inspired many variations; well known examples include Any Drink Called For, The Bar Act, Satan's Barman, and Think-a-Drink. During the temperance movement it became The Obliging Tea Kettle, and the modern Magic Tea Kettle remains a common prop available at most magic stores. A slight variation is the Magic Funnel. Today the trick is normally performed for children, although some stand-up shows retain a variation.
A powder is a dry, bulk solid composed of many very fine particles that may flow freely when shaken or tilted. Powders are a special sub-class of granular materials, although the terms powder and granular are sometimes used to distinguish separate classes of material. In particular, powders refer to those granular materials that have the finer grain sizes, and that therefore have a greater tendency to form clumps when flowing. Granulars refers to the coarser granular materials that do not tend to form clumps except when wet.
Polka dot paint is a paint of "polka dot color", i.e., a paint which paints an object with a polka dot pattern.
