Exploding Balloons of Death and Destruction

[MonkeyFoo]

OK, so I electrolyzed water into its flammable/explosive components: hydrogen and oxygen gases. My apparatus stored the gases in a balloon, which I removed and exploded. I made a video, and set it to some FFR music. My question is: how can I attach a video? The window that is supposed to tell me the acceptable sizes and extensions is broken for me, does anybody know what I can use? Thanks, as soon as I can post the video I'll explain the simple setup to make the balloons.
