One of our boys' favorite things to do in winter is decorate the snow. I just buy plastic spray bottles from the travel section at Target. They are just over $1 each. I let them each pick out their color of bottle. Then you just fill them with water, add a few drops of food coloring, and they head outside to be snow artists!

I love that this is such a fun and cheap activity for them. They also get a clean canvas whenever it snows again. Although, we've only had a few snowfalls this season. If it is really cold and they are out there for too long the tube tends to freeze up so we just run a bit of hot water through it for the next fill. So much fun!
