Airzooka Interesse_The Witcher Let all the scientists inThe Airzooka is an air cannon with which you can shoot an "air ball" up to 6m. It consists of a large plastic tube with a diameter of almost 30cm, at one end of which there is a large plastic foil that can be jerked loose using a rubber trigger. This creates an air blast that will make your victim's hair stand on end. A perfect geek tool :)
