I frequently look for party tips which are unique and out of the box. I find that Youtube is normally a good resource for this kind of ideas. All you will have to do is go to Youtube and perform a search for "event tips" and you can see several hours worth of videos with various excellent advices. The trouble is, who has the amount of time to view them all? So I am on a continuous mission to put together some details to save me and hopefully others some time.
Here is an awesome video with some insane party ideas - https://www.youtube.com/watch?v=wUlJSgYGmFw
