Ice.

As you would expect in a lockdown we have been nowhere.  Nothing in the day required essential movement away from the house and garden.  Mid morning I was wandering round the garden thinking about blip.  The temperature was well above freezing.

In the shadows on the patio a bucket of water caught my eye as the sun just got above the shed.  There was still ice on the bucket and the pattern was clearly showing.   Blip sorted.
