Snake oil salespeople may use "technobabble" to sell their product since cryptography is a complicated subject. [2] "Unbreakable" Claims of a system or cryptographic method being "unbreakable" are always false (or true under some limited set of conditions), and are generally considered a sure sign of snake oil.

Storm oil is described as nearly water-insoluble oil acting as a surfactant, and has been used since ancient times to smooth ocean waves. [ 1 ] [ 2 ] It has been historically employed to facilitate sea rescues and improve navigational safety, involving pouring the oil onto the ocean surface to reduce wave intensity.
A sample of synthetic motor oil. Synthetic oil is a lubricant consisting of chemical compounds that are artificially modified or synthesised. Synthetic oil is used as a substitute for petroleum-refined oils when operating in extreme temperature, in metal stamping to provide environmental and other benefits, and to lubricate pendulum clocks.
Oil-immersion objectives are used only at very large magnifications that require high resolving power. Objectives with high-power magnification have short focal lengths, facilitating the use of oil. The oil is applied to the specimen (conventional microscope), and the stage is raised, immersing the objective in oil. (In inverted microscopes the ...
A bottle of whale oil. Whale oil is oil obtained from the blubber of whales. [1] Oil from the bowhead whale was sometimes known as train-oil, which comes from the Dutch word traan ("tear drop"). Sperm oil, a special kind of oil obtained from the head cavities of sperm whales, differs chemically from ordinary whale oil: it is composed mostly of ...
Hydrogenation and thermal dissolution (reactive fluid processes) extract the oil using hydrogen donors, solvents, or a combination of these. Thermal dissolution involves the application of solvents at elevated temperatures and pressures, increasing oil output by cracking the dissolved organic matter. Different methods produce shale oil with ...
According to women’s health expert Dr. Jennifer Wider, “oil-based lubricants can destroy the integrity of latex condoms.” That includes anything with oil in it, such as lotion or petroleum ...
Eventually the steam condenses to hot water; in the steam zone the oil evaporates, and in the hot water zone the oil expands. As a result, the oil expands, the viscosity drops, and the permeability increases. To ensure success the process has to be cyclical. This is the principal enhanced oil recovery program in use today.
