The "Zero Blaster" is a fairly fun toy that makes smoke rings and projects them some 6 to 10 feet. For best visibility and accuracy, use in a darkend room without any drafts. Make sure to read and follow the directions for best results. The included fluid does last a good long time.This is a toy that will get a lot use when you first get it, and then likely be put aside. We pick it up every few months and play with it.Recommended!
