Hey there! These (hopefully) will show you how to make your very own Ranger beads, used by the US Army. They cost a pretty penny at stores (The one on the left cost me $12! *sigh*), but you can make them for much, much less obviously.
Also called "Pace Counter beads", they're used to keep track of how far you've gone while doing land navigation. Great for Scouts, back-packers, people who like dangling bits of string with beads on it...
Step 1: What You Need
You don't need too much to make Ranger beads. Really, only three things...
550 Cord: A staple of any soldier. I've heard it called "Parachute Cord" too. You can find a 50ft roll of it at any military surplus store for two or three dollars. You should be able to find it at a regular box store too.
Beads: Just about any type will do. I have yet to find the "official" shell-type beads anywhere, but it's not important; as long as they fit through the rope (some guys in my squad have cool-looking skull beads on theirs).
Matches: A lighter will work too. Anything that produces a small, fairly controlled flame. :)
Okay, now that you have that, let's get started!
