When I originally clicked on this video from the Slow Mo Guys via a Tweet from The Huffington Post I saw that it was about 5 minutes long and didn't think I would make it through to see the end. Three fourths of the way my attention was lost, but I did feel that I needed a pay off for the time I had already invested. It was worth it. Watch this vid, or at least skip ahead to the 4 minute mark.
The way the water splits the balloon and the shapes it makes as it's released is magical to watch in slow motion.
Here is a screen shot of the best part, it's worth watching in video if you have the time.
