I often try to find party ideas which are unusual and out of the box. I found that Youtube is usually a good resource of such tips. All you need to do is check out Youtube and perform a search for "event tips" and you are going to find several hours worth of videos clips with a lot of excellent tips. The problem is, who has the amount of time to view them all? So I am on a constant mission to gather some notes in order to save me and hopefully other people some time.
Here is a great video with some crazy party ideas - https://www.youtube.com/watch?v=wUlJSgYGmFw
