How to Preserve Our Power Cords

D.Gustin proposes a nice trick, aka "bidouille" to preserve our power cords of our power unit or iPod cables, known to become quickly curled before degrading irreversibly.

To avoid that it becomes as the c able shown on this photo and lead to a short circuit, he offers an easy way, by recycling the metal spring found in pencil. You simply insert it along the cord, and then install it in the critical area. That's it, so simple and so efficient.
