A mashup of two inspirations:
1 - My Day, Yesterday group on Flickr.
2 - Charity:Water
My Day, Yesterday videos are two to three-second video clips, raw audio, strung together to sum up your day. I've done a couple of those.
This time, I was thinking about how much clean, safe, drinkable water I use in a day and don't even notice. So this is My Day, Yesterday - in water.
