Bumper Stickers
A bumper sticker is an adhesive label or sticker with a message, intended to be attached to the bumper of an automobile and to be read by the occupants of other vehicles—although they are often stuck onto other objects. Most bumper stickers are about 25.4 cm by 7.6 cm (10 in by 3 in) and are often made of PVC. Purpose Bumper stickers can be commercial, religious, secular, humorous, or in support of a sports team or other organization. They may promote or oppose a particular philosophical or political position. In some countries, such as the United States, bumper stickers are a popular way of showing support for a candidate for a government seat and become more common during election years. In others, such as the United Kingdom, they are rarely seen in any form. One variety of bumper sticker is the country tag. This is typically used for cars crossing international borders, and is overseen by the United Nations as the ''Distinguishing Signs of Vehicles in Internati ...

Social Psychologist
Social psychology is the scientific study of how thoughts, feelings, and behaviors are influenced by the real or imagined presence of other people or by social norms. Social psychologists typically explain human behavior as a result of the relationship between mind, mental states and social situations, studying the social conditions under which thoughts, feelings, and behaviors occur, and how these variables influence Social relation, social interactions. History Although issues in social psychology have been discussed in philosophy for much of human history, the scientific discipline of social psychology formally began in the late 19th to early 20th century. 19th century In the 19th century, social psychology began to emerge from the larger field of psychology. At the time, many psychologists were concerned with developing concrete explanations for the different aspects of human nature. They attempted to discover concrete cause-and-effect relationships that explained soc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bob Switzer
Robert C. Switzer (19 May 1914 – 20 August 1997) was an American inventor, businessman and environmentalist. Switzer was co-inventor of the first black light fluorescent paint along with his brother Joseph Switzer and the inventor of the Magnaglo process for nondestructive flaw-detection in machined parts. The brothers founded the Day-Glo Color Corp. in 1946 to develop and manufacture fluorescent paints, pigments and other products. Biography Early life Switzer was born in Fromberg, Montana, to parents Maud (Slocum) and Emmet Switzer and was raised in Berkeley California. In 1932, he received a scholarship from the Scaife Scholarship Foundation of Oakland, California, so he attended the College of Chemistry at the University of California, Berkeley, in hopes of becoming a physician. During the summer of 1933, while working to unload tomatoes from a freight car at a H. J. Heinz Company laboratory in Berkeley, California, Switzer fell and suffered several serious injur ...

Blacklight Paint
Black light paint or black light fluorescent paint is luminous paint that glows under a black light. It is based on pigments that respond to light in the ultraviolet segment of the electromagnetic spectrum. The paint may or may not be colorful under ordinary light. Black light paint should not be confused with phosphorescent (glow-in-the-dark) or daylight fluorescent paint. History The invention of black light paint is attributed to brothers Joseph and Robert Switzer in the 1930s. After a fall, Robert suffered a severe head injury that resulted in a severed optic nerve. His doctor confined him to a dark room while he waited for his sight to recover. Joseph, who was a chemistry major at the University of California, Berkeley, worked with Robert to investigate fluorescent compounds. They brought a black light into the storeroom of their father's drugstore looking for naturally fluorescing organic compounds and mixed those compounds with shellac to develop the first black light f ...

World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Decal
A decal (, , ) or transfer is a plastic, cloth, paper, or ceramic substrate that has printed on it a pattern or image that can be moved to another surface upon contact, usually with the aid of heat or water. The word is short for ''decalcomania'', a decorative technique by which engravings and prints are transferred to pottery or other materials. The technique was invented by Simon François Ravenet, an engraver from France who later moved to England and perfected the process he called "décalquer" (which means "to copy by tracing"); it became widespread during the decal craze or mania of the late 19th century. Properties The term "decal" refers to the mass-produced art transfer in two different states: 1. As manufactured, which consists of the artwork printed on the upper side of a paper or film label stock, temporarily affixed by a typically water or heat soluble adhesive to the upper side of a silicone- or other release agent-coated paper or film backing stock.

Meramec Caverns
Meramec Caverns is the collective name for a cavern system in the Ozarks, near Stanton, Missouri. The caverns were formed from the erosion of large limestone deposits over millions of years. Pre-Columbian Native American artifacts have been found in the caverns. Currently the cavern system is a tourist attraction, with more than fifty billboards along Interstate 44 and is considered one of the primary attractions along former U.S. Highway 66. Meramec Caverns is the most-visited cave in Missouri with some 150,000 visitors annually. History The Meramec Caverns have existed for the past 400 million years, slowly forming through deposits of limestone. In centuries past, Native Americans used the cavern system for shelter. The first cave west of the Mississippi River to be explored by Europeans, it was first visited in 1722 by a French miner. Meramec Caverns was a station on the Underground Railroad. Thousands of runaway slaves were reportedly housed there.Daily Standard, Sike ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Paint Thinner
A paint thinner is a solvent used to thin oil-based paints. Solvents labeled "paint thinner" are usually mineral spirits having a flash point at about 40 °C (104 °F), the same as some popular brands of charcoal starter. Common solvents historically used as paint thinners include: * Mineral spirits (North America)/White spirit (United Kingdom and Ireland) * Acetone * Turpentine * Naphtha * Toluene * Lacquer thinner * Methyl ethyl ketone (MEK) * Dimethylformamide (DMF) * 2-Butoxyethanol, or any of the other glycol ethers Less common solvents used as paint thinner include: * Ethylbenzene * Xylene * ''n''-Butyl acetate * Butanol Exposure to vapors created by paint containing thinner or its cleanup may be hazardous. The American Conference of Governmental Industrial Hygienists has established threshold limit values (TLVs) for most of these compounds. TLV is defined as the maximum concentration in air which can be breathed by a normal person (i.e., excluding children, p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
WD-40
WD-40 is an American brand and the trademark of a penetrating oil manufactured by the WD-40 Company based in San Diego, California. The formula for WD-40 was invented for the Rocket Chemical Company as early as 1953 before it evolved into the WD-40 Company. WD-40 became available as a commercial product in 1961. It acts as a lubricant, rust preventive, penetrant and moisture displacer. There are specialized products that perform better than WD-40 in each of these uses, but WD-40's flexibility has given it fame as a jack of all trades. WD-40 stands for Water Displacement, 40th formula. It is a successful product to this day, with steady growth in net income from $27 million in 2008 to $70.2 million in 2021. In 2014, it was inducted into the International Air & Space Hall of Fame at the San Diego Air & Space Museum. History Sources credit different people with inventing WD-40 formula in 1953 as part of the Rocket Chemical Company (later renamed to WD-40 Company), in San Die ...

Heat Gun
A heat gun is a device used to emit a stream of hot air, usually at temperatures between 100 °C and 550 °C (200-1000 °F), with some hotter models running around 760 °C (1400 °F), which can be held by hand. Heat guns usually have the form of an elongated body pointing at what is to be heated, with a handle fixed to it at right angles and a pistol grip trigger in the same pistol form factor as many other power tools. Though it shares similarities to a hair dryer, it is not meant as a substitute for the latter, which safely spreads out the heat out across its nozzle to prevent scalp burning and has a limited temperature range, while heat guns have a concentrated element and nozzle, along with higher temperatures, which can easily scald the scalp or catch the hair on fire. Construction A heat gun comprises a source of heat, usually an electrically heated element or a propane/liquified petroleum gas, a mechanism to move the hot air such as an elect ...

Penetrating Oil
Penetrating oil, also known as penetrating fluid, is very low-viscosity oil. It can be used to free rusted mechanical parts (such as nuts and bolts) so that they can be removed, because it can penetrate into the narrow space between the threads of two parts. It can also be used as a cleaner; however, it should not be used as a general-purpose lubricant or a corrosion Corrosion is a natural process that converts a refined metal into a more chemically stable oxide. It is the gradual deterioration of materials (usually a metal) by chemical or electrochemical reaction with their environment. Corrosion engi ... stopper. Using penetrating fluids as general-purpose lubricants is not advisable, because such oils are relatively volatile. As a result, much of the penetrating oil will evaporate in a short amount of time, leaving little residual lubricant. Other uses include removing chewing gum and adhesive stickers, and lessening friction on metal-stringed musical instruments. ...
