Gel Blaster Starfire Gellets are small, water based self absorbing balls or water beads that glow in the dark. Starfire Gellets, when fully hydrated, reach the ideal size of 7.5mm which is perfect for enjoying night time gameplay with official Gel Blaster Starfire products. They disintegrate on impact and the glowing particles begin to dehydrate leaving no mess, no cleanup, and no worries. The Starfire Blaster (or Starfire Activator accessory) is necessary to fully charge your Gellets for extreme night time play, giving you a glowing tracer effect. Specialized formulation 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 5000 pack of glow in the dark Starfire Gellets. Failing to completely hydrate 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 1-gallon bucket works great for hydrating a 5000 Gellet pack. 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.
