Intro: Easy Emergency Extendable Mirror
A small mirror, a carpenter's folding rule, and duck tape are all I needed to give myself a mirror on a stick. The makeshift tool assembles in about two minutes, the length and mirror angle are adjustable, and the component parts can go back to their original purposes afterward. I have found it a great aid in checking the battery acid level in the back row of my house batteries, a regular chore for anyone using off-grid solar power. I'm thinking it might be of use for a number of other purposes as well.
