Gear up with Gelbee blasters and accessories for full-on trouble-free fun! Once you’ve got your Gelbee blaster, getting ready for fun is simple. Gelbee blasters fire tiny Super Absorbent Polymer (SAP) gel BBs. Just soak them in water and they expand to 10x their original size—and be ready for loading and firing! Gel BBs are eco-friendly, non-toxic, non-staining, and non-irritating. Even fired at 120 feet-per-second, they only sting enough to let you know you’ve been tagged. They won’t ruin your clothes, mess up your house, or pollute the neighborhood. Think of them like extra tiny water balloons that dissolve back into the earth.
