I regularly seek out party ideas that are unusual and out of the box. I learned that Youtube is generally a great resource for these kinds of ideas. All you have to do is visit Youtube and perform a search for "birthday party suggestions" and you can find many hours worth of movies with plenty of awesome tips. The problem is, who has time to watch them all? So I am on a constant mission to collect some notes so as to save me and also perhaps others some time.
Here is a great video with some insane party ideas - https://www.youtube.com/watch?v=wUlJSgYGmFw
Hope you see a few great ideas for your upcoming event on Youtube!
