Picture of Airsoft Pen Grenade (CHEAP TO MAKE)
Are you tired of making airsoft grenades with Easter eggs that are overly anticipated ,and don't work or do work and only go 5 inches. I am so I made this. It cost around 2 bucks and works fairly well for the cost.

Step 1: Get Materials

You will need airsoft bbs, cheap pen, something to take pen apart if needed, firecracker, and maybe some paper.
