The light of a summer's evening caught these bubbles outside my neighborhood market. They were promoting a solar oven that was baking cookies and was about the size of a double-wide kid's bicycle carrier. Very cool idea…but they had to keep moving it around the parking lot as the sun got lower and lower? Is this practical? Not all good ideas are practical…I'll leave it at that. Hope you are enjoying your bubbles of summer, this week of the solstice.
