The kids have never had a cool toy quite like this (nor adults for that matter). The ZERO Blaster is the coolest ray gun ever. Brightly colored, translucent, thick durable plastic lets you view the mechanics on the inside. Turn it on, press the fog chamber button and watch as the liquid fog suddenly turns into a billow of white fog (quickly dissipating, slightly scented cherry fog of course) inside the "Toroidal Vortex". Now you're ready to blast away like a real space alien. Just pull the trigger. Before you know it you'll be emulating your favorite science fiction hero from another planet. Ray gun even lights up every time you fire off a round of fog rings. ZAP bad guys with 6" rings from an incredible distance of 14 feet away. Then watch as the fog vanishes into thin air leaving behind nothing but the slight hint of cherry. Uses the same type of fog fluid used in most model trains. 6AA batteries not included. Replacement liquid fog can be easily found at most hobby stores.
