Hello geeky kids, this one is especially for you. This exciting and simplest of DIY project will make you construe the directions and save you from getting lost while you explore the unknown during your secret expeditions. All you need is a small magnet and an old CD, which, of late, you’ve been using as a Frisbee.



Just glue the magnet on the CD with its pole facing outwards and place in any small vessel with water; your compass is ready.



Thanks: Howtern
