Back in high school I used to play wargames with my classmates all the time — you know, the kind with BB pellets. Times changed, and BB guns are basically done for in mainland China. So recently a classmate dragged me out to play wargames again. Times changed again, and now it’s gel blasters. There are two kinds of gel blasters right now: gravity-fed and magazine-fed. Gravity-fed is the simple one — the BBs just sink down under their own weight. Like this Stedi 1911 pistol.
