I usually seek out party tips that are out of the ordinary and out of the box. I learned that Youtube is without a doubt a good source for this sort of tips. All you will have to do is go to Youtube and perform a search for "birthday party suggestions" and you can find hours and hours worth of videos clips with lots of good points. The problem is, who exactly has time to watch them all? So I am on a constant mission to gather some details to save me and hopefully other people some time.
Here is an awesome video with some insane party ideas - https://www.youtube.com/watch?v=wUlJSgYGmFw
