Gel blaster

A gel ball 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 pot/vase floriculture. Gel ball blasters are often played in CQB-style shooting skirmishes similar to paintball by squads or local clubs of enthusiasts often referred to as "gelballers", but follow an airsoft-like honor-based gameplay 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. In addition to safety gear such as eye protections, the sport is heavily regulated on the field and players must adhere to safety rules. The general design of gel ball blasters is very similar to airsoft guns, usually comprising a coil spring-loaded piston air pump, with a T-piece ahead of the pump outlet to feed gel beads. The spring-piston pump is either manually cocked (like a spring-piston gun) or more commonly driven by an electric motor-gearbox assembly powered by batteries (mostly identical to airsoft automatic electric guns (AEG)). Whilst the pressure output is identical to most airsoft guns via the use of compressed air, the uneven spherical shape, less weight and greater size of the projectile results in lower muzzle velocity than most airsoft guns. This nature of the gel ball external and terminal ballistics make them much safer to play with (although protective eyewear is still recommended) and very unlikely to cause any property damage. The gel beads are also very cheap, easily transported in packets and only require soaking in water for a few hours prior to playing.
