I typically look for party tips that are out of the ordinary and out of the box. I found that Youtube is truly a great resource for this sort of ideas. All you have to do is check out Youtube and perform a search for "birthday party ideas" and you will see hours worth of videos clips with lots of good suggestions. The problem is, who has the amount of time to watch them all? So I am on a regular quest to collect some notes in order to save me and also perhaps other people some time.
Here is a great video with some insane party ideas - https://www.youtube.com/watch?v=wUlJSgYGmFw
