Very small, compact NERF toy gun, because of their shot power does not need to hide behind the big models. Cheap to buy, very handy, little things are likely to get broken. Ideal as inconspicuous secondary "weapon" that can accommodate anywhere, and with which you can surprise the colleagues in the office well ;-)! For pedagogical review of NERF guns in general I want to just say: 30 years ago it was the bow and arrow etc. at each other, the risk of injury was in my opinion higher than in those foam projectiles. In addition, basic rules should be discussed with the children (not aim at the head (eyes), Pets not shoot, etc.). Cops and robbers games have always existed, and it will probably always be. At least the boys and girls move in this game. Maybe even outside in the fresh air! A not to be underestimated advantage in times of smartphone and console games! Maybe you should think about all concerns despite times.
