How to make a Viking Sun Compass!

Picture of How to make a Viking Sun Compass!
Even though vikings were great at navigating the sea, even they got lost trying to find North while at sea. When they did, they made a compass using just a block of wood, a nail, a pencil, and the sun! You too can channel your inner viking, by making a Sun Compass! The compass will only last for a few days, since the earth is constantly moving around the sun, and changing its position, causing the shadow to now be in a new orientation. By using a bigger piece of wood, you can create a compass that works everyday, by marking it weekly.

Step 2: Multitasking

Find the halfway point on the board, and place an X mark at the back of the board. To measure out the midpoint, place the ruler or tape measure at one end of the board. Then measure the length of the board, and divide it by 2. You now know the midpoint between the two ends. Just measure to that distance, and make an X. Place the two planks of wood on the saw horse. Once marked, place your 1X5 block of wood on top of the wood planks. 

Step 3: STOP! Hammer time!

After marking the midpoint at the back of the board, place a nail on the mark, and hold it steady. Then take the hammer and slowly beat it in. Once the nail is all the way through, be careful when taking it off, or you could get a nasty prick. Make sure it is a new nail, and not rusty, just in case you touch and cut yourself. Vikings didn't have tetnis shots! (MAY NEED ADULT HELP!)

I bet it does. I chose to make one for my Physics and Engineering class! We had to find an Instructable of what we wanted to build, and then make our own! We also read your tip guide on how to write an Instructablem, which was really helpful! :D

How do you ensure that the gnomon is vertical when you point the sun? If it tilts, the measure could send you to other part of the world, not where you want go.

No big deal. The shortest shadow of everything indicate the true North. Better than compass.
