Gel Blaster Starfire Gellets disintegrate on contact and the glowing particles begin to dehydrate leaving no mess, no cleanup, and no worries! Included are two 5,000 packs for a total of 10,000 7.5mm Starfire glow in the dark Gellets.Starfire Gellets are a specialized formulation and must be soaked in water for at least 4 hours to fully expand in size. You will need half a gallon of water to fully hydrate a single 5,000 pack of glow in the dark Gellets. Failing to completely hydrate the Starfire Gellets may cause your Gel Blaster to function poorly.Gel Blaster Gellets expand 10x their size so make sure you use a big enough container. A one gallon bucket works great for hydrating a 5,000 Gellet pack. The Gel Blaster Gellet Depot and Collapsible Gellet Tub are the perfect solution to making, straining, and storing your Gellets! (sold separately). Once fully hydrated, strain out any excess water to avoid causing any issues with your blaster, and load your hopper. The specialized nature of Starfire Gellets may cause them to lose their full glow capability over time, so make sure to only hydrate what you plan on using.
