Sungdogs are a type of phenomena that makes it look like 3 suns in the sky. 2 Small ones and in between 1 large Sun. This was sometimes refered as the apocalypse. However, this is casued by ice crystals in the

apmosphere, Cirrus clouds contain ice crystals.


They form when The Sun's light interacts with ice crystals, these crystals are hexagonal-shaped. When it interacts with sunlight, it bounces off the other diagonal sides of the crystals' shape.


Try preforming it with these ingredients:

Projector Beam, Jam Jar, and a white board.

Place the board standing on a table, turn on the projector beam at it, you will se that it represents the Sun. Put the Jam Jar standing in the way of the light. You will see an image on both sides at about 22 degress.
