Gel blaster
A gel ball blaster, also known as a water gel blaster, orbeez gun, gel gun, gel shooter, gel marker, hydro gel blaster, water bead blaster or gelsoft gun, is a toy gun similar in design to airsoft guns, but the projectiles they shoot are 7–8mm (depending on the replica) superabsorbent polymer water beads (most commonly sodium polyacrylate, colloquially called gel balls, water beads, hydrogel balls, water bullets or simply gels), which are often sold commercially as moisture retainers for gardening and pot/vase floriculture. It is popular in Australia and mainland China, where normal airsoft equipment is banned or hard to obtain.
