I frequently hunt for event tips which are unique and out of the box. I think that Youtube is truly a good source of this type of tips. All you will have to do is go to Youtube and do a search for "birthday party tips" and you are going to see many hours worth of online videos with lots of very good advices. The issue is, who has the time to view them all? So I am on a constant mission to compile some details so as to save me and also hopefully others some time.
Here is a great video with some insane party ideas - https://www.youtube.com/watch?v=wUlJSgYGmFw
