I commonly look out for event ideas which are out of the ordinary and out of the box. I found that Youtube is a wonderful source for these types of ideas. All you need to do is browse through Youtube and do a search for "party tips" and you can find many hours worth of movies with various wonderful points. The trouble is, who has enough time to watch them all? So I am on a regular quest to gather some details so as to save me and also perhaps other people some time.
Here is an awesome video with some crazy party ideas - https://www.youtube.com/watch?v=wUlJSgYGmFw
I hope you see a number of great tips for your upcoming celebration on Youtube!
