Winter Wonderland Sweet Sixteen

Hey! I`m throwing a sweet sixteen in January and my theme is winter wonderland and when I walk in I want fake snow to be falling as I walk in to let it snow by jessica simpson. Any ideas?? Right now its just a fairytale because I have no idea how to get fake falling snow. If anyone can help with this or give me ideas for my sweet sixteen I would be so happy!
Thanks alot,
