Sunstone was used over a thousand years ago by the Vikings to navigate across the sea Icelandic spa crystal is able to polarise the light of the sun you put one black dot on one side of it and from the other side it there Crystal splits into two when the two dots are of equal brightness that is whether sun is, anywhere away from the Sun and one of them goes dark . As I said this was used to navigate the oceans before compasses were invented if you know where the sun is you can work out which direction you're going to the west. You will also need compass board.

Thank you. So simple tool for something very complex. Must make the navigation quick

This would make a nifty souvenir for people who like crystals or historical artifacts.

It's boxing day 2023 and old Dave has solved the riddle of the sunstone! Look at the stone! The cracks within the stone function like the dots except the colours are in opposition to the dots. I have two sun stones but neither are cracked within like yours. I only noticed after watching this video! Look at the cracks!!!!!!!! All videos I've seen use tape, dots, lines eff but they are additions to the stone. Look at the cracks!!!!!!!

Great video, actually shows how it works!!! My sons learning about the Vikings in school.🤗

Have you found this to work even in moderate to heavy cloud cover? I was under the impression that was it's main use, but most of the videos demonstrate in relatively clear skies (probably for ease of filming).

Thank you for explaining how it works instead of bs videos with just stick videos and photos.
|
Thanks for this

Northern Atlantic waters can have twilight for 5 hours, so can you tell me how long you can track the sun after sunset and prox were you live/time of recording ?
I have retired in Spain, and could only use it 40-45 min after sunset mid summer.
I have tried to look for data on latitude vs how long it can be seen, but nobody seem to have collected the data yet..
|
Oh great, it shows which direction the sun is
|
Is there one dot or two dots? One on each side?
|
COOOOOOL!! Maybe it’s not so coincidental that I love crystals and that my last name means Viking 😅
|
Where you get yours ? Any idea where to find real good working ones ?
|
Watching this cuz dr. Stone 😂
|
It looks kinda like plastic technology
|
Thank you, unfortunately this is completely wrong. Absolutely useless attempt. I'm sorry. you didn't understand the physics principle.

Thank you. FINALLY....someone who shows HOW it was used and how to make mine do the same. No one mentions you need to put an opaque black dot on one side of the stone. Only you did that. Thank you again.
