Paul and I met Tim and Ernie before sunrise to do frozen soap bubbles. I had seen some incredible images of this the year before and really wanted to try it out. Tim knew the finer points, so we were fairly successful. The main thing is it needs to be cold. I've read that around 10 to 15 degrees is best. On the way out, we saw a sign at 9 degrees and a couple of hours later on the way home it was 10.
