sure, you can make one at home with a box but this is way cooler. A gun that shoots laser-like fog smoke rings. The rings are 2 to 6 inch in diameter and they are of course non toxic. The liquid used is the same liquid that is used in Hollywood movies to make special effects fog. You and your kids will have countless hours of fun with this fog blaster. You’ll be captivated by their beauty and mesmerized by the myriad shapes you’ll discover in every fog ring you create.
