Introduction: Homemade Sundial
I decided to show how to make a homemade sundial that tells time by the hour.
Step 1: Materials
A Right Triangle Shaped Item or a Straight Stick
Dirt or Sand
Step 2: Don't Cross This Line!
Using the compass, find north, then draw a straight line towards north. Then draw another line horizontally through the vertical line. Set the triangle on the line facing north; if you are using a stick, jam it into the center of the lines. You can then use a watch to add on the exact hours. The lines are set up in this pattern: North is 12 o'clock, East is 3 o'clock, South is 6 o'clock and West is 9 o'clock.
Step 3: Finish
This sundial could be used in an emergency situation or could just be a fun little project. Please leave a comment.

The position of the sun will change so the time wont be accurate. You have to angle the gnomon or the base for you location specifically. see an example here...https://www.instructables.com/id/Sundial-From-Scrap...
Otherwise its a very cool survival clock

Thanks! The triangle method will operate for a quick check of time. For all day time telling, the stick will work best.
