Ifyou have a burning desire to know the origins of caustic, you're already well on your way to figuring it out. Caustic was formed in Middle English as an adjective describing chemical substances, such as lime and lye, that are capable of destroying or eating away at something. The word is based on the Latin adjective causticus, which itself comes ultimately from the Greek verb kaiein, meaning "to burn." In time, caustic was baked into the English language as an adjective describing people or things (such as wit or remarks) that are bitingly sarcastic. Other kaiein descendants in English include cautery and cauterize, causalgia (a burning pain caused by nerve damage), and encaustic (a kind of paint that is heated after it's applied).

Vlad is truly a magician. I binged all of his videos this past weekend hoping to find a solution. This was the closest but I specifically need it to look like water caustics. I thought Photoshop was an option but it needs to be done over a 360 render so that complicates things a little. The pano editing capability in Photoshop is super limited, especially with layers and blending modes.
At the end of the day, I was able to accomplish it in Photoshop using the warp tool to get the general effect. It would be great to have a projector light type in the future... add it to the list of a million Enscape wishes!

If any person maliciously causes any other person bodily injury by means of any acid, lye or other caustic substance or agent or use of any explosive or fire, he shall be guilty of a felony and shall be punished by confinement in a state correctional facility for a period of not less than five years nor more than thirty years. If such act is done unlawfully but not maliciously, the offender shall be guilty of a Class 6 felony.
At room temperature, anhydrous sodium hydroxide is a white crystalline, odorless solid that absorbs moisture from the air. It is produced as flakes, pellets, sticks, and cakes. When dissolved in water or neutralized with acid, it liberates substantial heat, which may be sufficient to ignite combustible materials. Sodium hydroxide is caustic and is one of several alkaline compounds referred to as "lye." It is generally used commercially as either the solid or as a 50% aqueous solution and should be stored in a cool, dry, well ventilated location separate from organic and oxidizing materials, acids, and metal powders.
Inhalation of sodium hydroxide dust, mist, or aerosol may cause irritation of the mucous membranes of the nose, throat, and respiratory tract. Sodium hydroxide is odorless; thus, odor provides no warning of hazardous concentrations. Mucous membrane irritation occurs at the OSHA PEL (2 mg/m3) and is generally an adequate warning property for acute exposure to sodium hydroxide. However, workers exposed to prolonged or recurrent mists or aerosols of sodium hydroxide can become somewhat tolerant of the irritant effects. Sodium hydroxide of sufficient strength can hydrolyze proteins in tissues and can kill cells in tissues.
Children exposed to the same levels of sodium hydroxide in air as adults may receive a larger dose because they have greater lung surface area:body weight ratios and increased minute volumes:weight ratios. In addition, they may be exposed to higher levels than adults in the same location because of their short stature and the higher levels of sodium hydroxide in air found nearer to the ground.
Exposure to sodium hydroxide solid or solution can cause skin and eye irritation. Direct contact with the solid or with concentrated solutions causes thermal and chemical burns leading to deep-tissue injuries. Very strong solutions of sodium hydroxide can hydrolyze proteins in the eyes, leading to severe burns and eye damage or, in extreme cases, blindness.
Sodium hydroxide is used to manufacture soaps, rayon, paper, explosives, dyestuffs, and petroleum products. It is also used in processing cotton fabric, laundering and bleaching, metal cleaning and processing, electroplating, oxide coating, and electrolytic extracting. It is commonly present in commercial drain and oven cleaners.
AIHA ERPG-2 (emergency response planning guideline) (maximum airborne concentration below which it is believed that nearly all individuals could be exposed for up to 1 hour without experiencing or developing irreversible or other serious health effects or symptoms which could impair an individual's ability to take protective action) = 5 mg/m3
Sodium hydroxide dissolves easily in water generating a great deal of heat. It reacts with acids (also generating a lot of heat); halogenated organic compounds; metals such as aluminum, tin, and zinc; and nitromethane. Sodium hydroxide is corrosive to most metals.
Sodium hydroxide is strongly irritating and corrosive. It can cause severe burns and permanent damage to any tissue that it comes in contact with. The extent of damage to the gastrointestinal tract may not be clear until several hours after ingestion. Inhaled sodium hydroxide can cause swelling of the larynx and an accumulation of fluid in the lungs. Contact with 25-50% solutions produces immediate irritation, while after contact with solutions of 4% or less, irritation may not develop for several hours. It may not be possible to correctly ascertain the degree of damage to eyes for up to 72 hours after exposure.
Inhalation of sodium hydroxide is immediately irritating to the respiratory tract. Swelling or spasms of the larynx leading to upper-airway obstruction and asphyxia can occur after high-dose inhalation. Inflammation of the lungs and an accumulation of fluid in the lungs may also occur.
Skin contact with solid sodium hydroxide or its concentrated solutions can cause severe burns with deep ulcerations. Burns appear soft and moist and are very painful. Although contact with concentrated solutions causes pain and irritation within 3 minutes, contact with dilute solutions may not cause symptoms for several hours.
Eye exposure may produce diffuse or localized blood vessel clots and an accumulation of fluid in the eye. Softening, sloughing, and ulcerations of the cornea may occur. Ulcerations may continue to progress for many days. Severe injury can lead to clouding of the eye surface and blindness.
Ingestion of sodium hydroxide can cause spontaneous vomiting, chest and abdominal pain, and difficulty swallowing with drooling. Corrosive injury to the mouth, throat, esophagus, and stomach is extremely rapid and may result in perforation, hemorrhage, and narrowing of the gastrointestinal tract.
Cancer of the esophagus has been reported 15 to 40 years after the formation of corrosion-induced strictures. However, it is believed that these cancers were the result of tissue destruction and scar formation rather than a direct cancer-causing action of sodium hydroxide.
Chronic exposure to dusts or mists of sodium hydroxide may lead to ulceration of the nasal passages. Chronic skin exposures can lead to dermatitis. Ingestion may lead to perforation of the gastrointestinal tract or stricture formation.
Sodium hydroxide dissociates within the body and would not reach the reproductive organs in an unchanged state. No data were located concerning reproductive endpoints in humans exposed to sodium hydroxide. Sodium hydroxide is not teratogenic in rats. Sodium hydroxide is not included in Reproductive and Developmental Toxicants, a 1991 report published by the U.S. General Accounting Office (GAO) that lists 30 chemicals of concern because of widely acknowledged reproductive and developmental consequences.
Rescuers should be trained and appropriately attired before entering the Hot Zone. If the proper equipment is not available, or if rescuers have not been trained in its use, assistance should be obtained from a local or regional HAZMAT team or other properly equipped response organization.
Respiratory Protection: Positive-pressure, self-contained breathing apparatus (SCBA) is recommended in response situations that involve exposure to potentially unsafe levels of sodium hydroxide.
If victims can walk, lead them out of the Hot Zone to the Decontamination Zone. Victims who are unable to walk may be removed on backboards or gurneys; if these are not available, carefully carry or drag victims to safety.
Quickly access for a patent airway, ensure adequate respiration and pulse. Stabilize the cervical spine with a collar and a backboard if trauma is suspected. Administer supplemental oxygen as required. Assist ventilation with a bag-valve-mask device if necessary.
Rapid decontamination is critical. Victims who are able may assist with their own decontamination. Rescuers should wear protective clothing and gloves while treating patients whose skin is contaminated with sodium hydroxide.
Immediately brush any solid material from clothes, skin, or hair while protecting the victim's eyes. Quickly remove contaminated clothing and flush exposed areas with water for at least 15 minutes. Double-bag contaminated clothing and personal belongings. Use caution to avoid hypothermia when decontaminating children or the elderly. Use blankets or warmers when appropriate.
Flush exposed or irritated eyes with plain water or saline for at least 30 minutes. Remove contact lenses if easily removable without additional trauma to the eye, otherwise sodium hydroxide trapped beneath the lens will continue to damage the eye. If pain or injury is evident, continue irrigation while transferring the victim to the Support Zone.
