I typically search for party ideas which are unique and out of the box. I think that Youtube is generally a wonderful resource of this type of tips. All you need to do is browse Youtube and perform a search for "birthday party ideas" and you are going to find several hours worth of video clips with plenty of good tips. The problem is, who exactly has the time to see them all? Thus I am on a continuous quest to compile 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
