Hack Of The Night : How to make a compass if you’re lost in the woods

This is one of those survival hacks that I hope you never have to use.  But if you ever find yourself lost in the woods, here's how to make a compass to find North.  I tried this after I saw Sir Anthony Hopkins do it in the movie "The Edge" and it totally works!  Btw, if you haven't seen that movie and want to watch a great thriller this weekend, I placed the trailer for the movie below.  This would even be fun to do if you have little ones to teach them about science and survival.

"The Edge" starring Sir Anthony Hopkins and Alec Baldwin
