I frequently want party ideas which are unique and out of the box. I find that Youtube is undoubtedly a good resource for these sorts of tips. All you will have to do is visit Youtube and do a search for "birthday party suggestions" and you are going to see several hours worth of video clips with lots of wonderful points. The trouble is, who has the amount of time to view them all? Thus I am on a regular mission to put together some notes in order to save me and perhaps other people some time.
Here is a great video with some crazy party ideas - https://www.youtube.com/watch?v=wUlJSgYGmFw
