This project will show you how you can make a simple compass with duct tape, a cork, a needle and a magnet: a floating needle compass. The benefit of this duct tape design is that the this compass can be rolled and stored neatly when not in use, a duct tape collapsible compass
; how cool is that?
This instructable will cover the process of making a compass with duct tape, as well as alternatives to all the materials used. So you'll never be far from some materials that will work instead of what's shown, even out in the wilderness.
Making your own compass is considered as a rite of passage for many scouts, and a staple for wildness survival along side of making a fire
and tying knots
. Don't plan of having any of these materials handy next time you go camping? You need to come more prepared
(read: bring duct tape)!
If you don't already know, compasses work on magnetism. The science is that our planet is just a really big magnet and creates a magnetic field that surrounds us an extends out into space, It's called the magnetosphere. This magnetic field isn't very strong, but is enough to orient a freely rotting magnet. By magnetizing a lightweight metal object and allowing it to rotate with low resistance we can determine which direction the magnetic poles of the earth are, using the known phenomenon that similar poles repelling while dissimilar poles attract.
Even if you think you know how to make a basic compass, it's wise to refresh yourself with themost important step.
Enough talk, let's make a duct tape compass!
