This is called frostflowers. It's a very rare ice-formation that grows on branches when the branch squeezes out water. It looks like cotton candy, but it melts like a snowflake when you touch it. It's really, really cool. This is the newspaper article about it. (In norwegian)http://www.aftenposten.no/viten/article1588588.ece
Eat some, post pix.
Cool
