Water Beads
Water crystal gel or water beads or gel beads is any gel which absorbs and contains a large amount of water. Water gel is usually in spherical form and composed of a water-absorbing superabsorbent polymer (SAP, also known as slush powder in dry form) such as a polyacrylamide (frequently sodium polyacrylate). Uses Water gels are used for: * Supplying water to small animals as an alternative to supplying water in a dish. Some small animals tend to fall into dishes of water and drown. * Watering or potting plants. * In vases of cut flowers * Use in gardens to save water.citation needed''] * Used as ammunition for gel blaster toy guns.

Wholesale Water Beads Blue
Wholesaling or distributing is the sale of goods or Merchandising, merchandise to retailers; to manufacturing, industrial, commercial, institutional or other professional business users; or to other wholesalers (wholesale businesses) and related subordinated services. In general, it is the sale of good (economics), goods in bulk sale, bulk to anyone, either a person or an organization, other than the end consumer of that merchandise. Wholesaling is buying goods in bulk quantity, usually directly from the manufacture or source, at a discounted rate. The retailer then sells the goods to the end consumer at a higher price making a profit. According to the United Nations Statistics Division, ''wholesale'' is the :wiktionary:resale, resale of new and used goods to retailers, to industrial, commercial, institutional or professional users, or to other wholesalers, or involves acting as an Law of agency, agent or broker in buying merchandise for, or selling merchandise to, such person ...

Absorption (chemistry)
In chemistry, absorption is a physical or chemical phenomenon or a process in which atoms, molecules or ions enter some bulk phase – liquid or solid material. This is a different process from adsorption, since molecules undergoing absorption are taken up by the volume, not by the surface (as in the case for adsorption). A more common definition is that "Absorption is a chemical or physical phenomenon in which the molecules, atoms and ions of the substance getting absorbed enters into the bulk phase (gas, liquid or solid) of the material in which it is taken up." A more general term is '' sorption'', which covers absorption, adsorption, and ion exchange. Absorption is a condition in which something takes in another substance. In many processes important in technology, the chemical absorption is used in place of the physical process, e.g., absorption of carbon dioxide by sodium hydroxide – such acid-base processes do not follow the Nernst partition law (see: solubility). ...

Orbeez
Expandable water toys (also grow-in-water toys or grow monsters) are novelty items made from a superabsorbent polymer. They are toys that expand after putting them into water for anything between a few hours up to several days, depending on size. They shrink in saltwater or when exposed to air. They are made from polymers that can absorb and retain extremely large amounts of a liquid relative to their own mass. Description Grow Monsters come in many different shapes and sizes. Reptiles and dinosaurs are common figures, but there are many others, such as: sharks, squid, seahorses, lobster, insects, humans, and mechas from popular anime are among them. Many of the companies that distribute them are Chinese and Dutch trading companies. Water Balz look like marbles, but expand to , the size of a racquetball, in water. Orbeez expand to in water. History The introduction and popularity of these toys has followed the development of superabsorbent polymers. In the early 1970s, the su ...

Polyacrylamide
Polyacrylamide (abbreviated as PAM) is a polymer with the formula (-CH2CHCONH2-). It has a linear-chain structure. PAM is highly water-absorbent, forming a soft gel when hydrated. In 2008, an estimated 750,000,000 kg were produced, mainly for water treatment and the paper and mineral industries. Physicochemical properties Polyacrylamide is a polyolefin. It can be viewed as polyethylene with amide substituents on alternating carbons. Unlike various nylons, polyacrylamide is not a polyamide because the amide groups are not in the polymer backbone. Owing to the presence of the amide (CONH2) groups, alternating carbon atoms in the backbone are stereogenic (colloquially: chiral). For this reason, polyacrylamide exists in atactic, syndiotactic, and isotactic forms, although this aspect is rarely discussed. The polymerization is initiated with radicals and is assumed to be stereorandom. Copolymers and modified polymers Linear polyacrylamide is a water-soluble polymer. Oth ...

Sodium Polyacrylate
Sodium polyacrylate (ACR, ASAP, or PAAS), also known as waterlock, is a sodium salt of polyacrylic acid with the chemical formula ��CH2−CH(CO2Na)−sub>n and has broad applications in consumer products. This super-absorbent polymer (SAP) has the ability to absorb 100 to 1000 times its mass in water. Sodium polyacrylate is an anionic polyelectrolyte with negatively charged carboxylic groups in the main chain. Sodium polyacrylate is a chemical polymer made up of chains of acrylate compounds. It contains sodium, which gives it the ability to absorb large amounts of water. When dissolved in water, it forms a thick and transparent solution due to the ionic interactions of the molecules. Sodium polyacrylate has many favorable mechanical properties. Some of these advantages include good mechanical stability, high heat resistance, and strong hydration. It has been used as an additive for food products including bread, juice, and ice cream. While sodium neutralized polyacrylic aci ...

Superabsorbent Polymer
A superabsorbent polymer (SAP) (also called slush powder) is a water-absorbing hydrophilic homopolymers or copolymers that can absorb and retain extremely large amounts of a liquid relative to its own mass. Water-absorbing polymers, which are classified as hydrogels when mixed, absorb aqueous solutions through hydrogen bonding with water molecules. A SAP's ability to absorb water depends on the ionic concentration of the aqueous solution. In deionized and distilled water, a SAP may absorb 300 times its weight (from 30 to 60 times its own volume) and can become up to 99.9% liquid, and when put into a 0.9% saline solution the absorbency drops to approximately 50 times its weight. The presence of valence cations in the solution impedes the polymer's ability to bond with the water molecule. The SAP's total absorbency and swelling capacity are controlled by the type and degree of cross-linkers used to make the gel. Low-density cross-linked SAPs generally have a higher absorbent ca ...

Flood
A flood is an overflow of water ( or rarely other fluids) that submerges land that is usually dry. In the sense of "flowing water", the word may also be applied to the inflow of the tide. Floods are an area of study of the discipline hydrology and are of significant concern in agriculture, civil engineering and public health. Human changes to the environment often increase the intensity and frequency of flooding, for example land use changes such as deforestation and removal of wetlands, changes in waterway course or flood controls such as with levees, and larger environmental issues such as climate change and sea level rise. In particular climate change's increased rainfall and extreme weather events increases the severity of other causes for flooding, resulting in more intense floods and increased flood risk. Flooding may occur as an overflow of water from water bodies, such as a river, lake, or ocean, in which the water overtops or breaks levees, resulting i ...

Diaper
A diaper /ˈdaɪpə(r)/ ( American and Canadian English) or a nappy ( Australian English, British English, and Hiberno-English) is a type of underwear that allows the wearer to urinate or defecate without using a toilet, by absorbing or containing waste products to prevent soiling of outer clothing or the external environment. When diapers become wet or soiled, they require changing, generally by a second person such as a parent or caregiver. Failure to change a diaper on a sufficiently regular basis can result in skin problems around the area covered by the diaper. Diapers are made of cloth or synthetic disposable materials. Cloth diapers are composed of layers of fabric such as cotton, hemp, bamboo, microfiber, or even plastic fibers such as PLA or PU, and can be washed and reused multiple times. Disposable diapers contain absorbent chemicals and are thrown away after use. Diapers are primarily worn by infants, toddlers who are not yet toilet trained, and by chi ...

Toy Gun
Toy guns are toys which imitate real guns, but are designed for recreational sport or casual play by children. From hand-carved wooden replicas to factory-produced pop guns From Gilroy Gardens and cap guns, toy guns come in all sizes, prices and materials such as wood, metal, plastic or any combination thereof. Many newer toy guns are brightly colored and oddly shaped to prevent them from being mistaken for real firearms. Types Wooden guns are made to resemble real guns. Often handmade, these toys may or may not have metal parts and are made with various levels of detail. Rubber band guns, are toy gun used to fire one or more rubber bands (or "elastic bands"). Rubber band guns are often used in live-action games such as Assassins, in which they are common and popular toy weapons. They are also common in offices and classrooms. Rubber band guns have been popular toys that date back to the invention of rubber bands, which were patented in England on March 17, 1845 by Ste ...

Water
Water (chemical formula ) is an inorganic, transparent, tasteless, odorless, and nearly colorless chemical substance, which is the main constituent of Earth's hydrosphere and the fluids of all known living organisms (in which it acts as a solvent). It is vital for all known forms of life, despite not providing food, energy or organic micronutrients. Its chemical formula, H2O, indicates that each of its molecules contains one oxygen and two hydrogen atoms, connected by covalent bonds. The hydrogen atoms are attached to the oxygen atom at an angle of 104.45°. "Water" is also the name of the liquid state of H2O at standard temperature and pressure. A number of natural states of water exist. It forms precipitation in the form of rain and aerosols in the form of fog. Clouds consist of suspended droplets of water and ice, its solid state. When finely divided, crystalline ice may precipitate in the form of snow. The gaseous state of water is steam or water vapor. W ...

Gel Blaster
A gel blaster, also known as a gel gun, gel shooter, gel marker, hydro marker, hydro blaster, water bead blaster or gelsoft, is a toy gun similar in design to airsoft guns, but the projectiles they shoot are superabsorbent polymer water beads (most commonly sodium polyacrylate, colloquially called water beads, hydrogel balls, gel balls, water bullets or simply gels), which are often sold commercially as moisture retainers for gardening and flowerpot, pot/vase floriculture. Gel blasters are often played in Close-quarters combat, CQB-style shooting sport, shooting skirmishes similar to paintball by squads or local clubs of enthusiasts often referred to as "gelballers", but follow an airsoft-like honor system, honor-based gameplay referee, umpiring system. MilSim games involving players wearing camouflage and dump pouches are very popular, while "SpeedGel" players are more casual with team jerseys and often wear paintball masks.
