Happy 4th of July (or any other day you care to celebrate)! In this video I show how to fold my Exploding Envelope. The background music (or shall I say 'noise'?) is my meanderings into the medium of human beat box humming which is humming and beatboxing at the same time. I also make a couple sound effects.
The Exploding Envelope is a model I designed and published in my book Origami to Astonish and Amuse sold here: http://amzn.to/13smJt7
