Don't use a green laser in the cold!

Does a green laser pointer stop working when it is cold? Or does it turn into an invisible laser? That is nice to know for safety reasons if you are using a green laser pointer to point out stars on a frost-clear night.
And what about those decorations lasers for your garden? Are they safe at a freezing winter night? Time to find out in this video!
