This image was taken by simply sticking a denture cleaning tablet to the bottom of a jug, and then pouring water in and taking a high shutter speed image of the bubbles rising. One of the reasons I chose to use this was because I actually got lucky with my lighting and there was a small beam of light peeking through the blinds that perfectly illuminated the bubbles rising. Once that happened I turned out all the other lights in the room and was able to snap a really cool shot!
