bubbles in black and white

I am burning a disc or four right now, and so while that's running in the background, why not share a few more pictures? Like the post below, these are from a week ago today. The specs: ISO 160, Aperture f/4, Shutter 1/250, Flash? Yes. Converted to B/W in Adobe Lightroom. I wonder what it is about bubbles that makes kids so dang happy... Don't think I've ever met a kid under 4 yrs. old who didn't think they were the absolute coolest thing ever.
