Finding Your Way by the Stars
Three short lessons on the oldest navigation: the star that stays put, measuring its height with your hand or a card on a string, and reading your latitude from the noon Sun.
For grown-ups, from what SextantForge teaches children at Spark & Anvil.
Make a kamal
You'll need: a piece of card about 5 by 8 cm, a metre of string, and a dark, clear sky.
- Make a small hole in the middle of the card and tie the string through it.
- Find Polaris: follow the two stars at the end of the Big Dipper's bowl upwards.
- Hold the string's end to your chin and slide the card out until its bottom touches the horizon and its top touches Polaris.
- Tie a knot where the string meets your chin. That knot is your home's latitude; check it on a map.
