It's been so cold these past few days that the marker in the back-porch thermometer has frozen permanently somewhere south of 23 degrees F. That translates to -5 degrees C which, when you read it, looks way colder than it really is.
But still, too cold for the icicles to melt. Or the snow, which keeps piling up.
On the positive side, these temperatures are perfect for freezing soap bubbles. If you've got some bubble mix left over from the summer, go outside on any day when it's below 32 degrees F (0 C) and try this: blow a bubble and then catch it on the bubble wand. Wait a few moments while it freezes - it should turn into a crystal ball before it shatters.
If you want to watch icy crystals form, dip a large loop in the bubble solution - but don't blow a bubble. Instead, watch the crystals grow. They should form a lattice structure.
