I often seek out party ideas which are out of the ordinary and out of the box. I find that Youtube is a very good source for these ideas. All you need to do is browse through Youtube and do a search for "event ideas" and you can find many hours worth of movies with many different excellent ideas. The trouble is, who has the time to see them all? So I am on a regular mission to collect some notes in order to save me and perhaps other people some time.
Here is a great video with some insane party ideas - https://www.youtube.com/watch?v=wUlJSgYGmFw
Hope you see some great ideas for your future party on Youtube!
