Hot Chocolate is the perfect companion for watching northern lights. Northern lights are caused by solar storms colliding with the atmosphere.
They can occur at any time, but we can only see them:
-at high latitudes
-when it’s dark
-when the sky’s are clear.
This is why we see them in Iceland in the winter and watching them is associated with being very cold. This is why many people take a flask of their favourite cocoa with them to keep them warm while viewing this beautiful phenomenon.
