This is a very simple to build but fun puzzle, that you can make as a present or for yourself. ;-)

You will need a minimum of materials and only a few basic tools.

(Since English is a second language for me, please forgive me for the spelling mistakes I might make)

Step 1: Materials

Because of the simplicity of this project you only need these few materials:

  • 4 beads
  • a piece of string (at least 40cm)
  • a small piece of wood (mine was about 10 x 5 x 0.8 cm)
