If you have a little time to spare and are handy with some very basic tools, you have enough to make yourself an awesome weekend. One of our favorite YouTube channels, Grant Thompson’s The King of Random, has a nice little two-hour project for you in his laser-guided blowgun. Now, before anything else, it should be said that the end result can be a little on the dangerous side, so do use caution (and your head) when using it. It’s basically a PVC tube, a reducer, and some tape, with ammo coming in the form of hot glue, sticky notes, and some finishing nails. One trip to the hardware store should get you all the item you need for hours of fun, and possibly some post-apocalyptic survival hunting.
