Homemade Sundial

About: I like inventing, experimenting, rockets, film making, and more! I consider myself a teenaged genius. I feel that with enough time I could build anything.

I decided to show how to make a homemade sundial that tells time by the hour.

Step 1: Materials

What’s Needed:

A Right Triangle Shaped Item or a Straight Stick

Dirt or Sand

Compass

Optional: Watch

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.

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