Garden spinner

On a grey, raw, cold day, I was well lagged to continue with some outdoor jobs, but nothing in the garden looked remotely like a possibility for blip. So here is a 5 year old spinner which, like the Geraniums, over Winters in the green house. Somewhat amazingly the light continues to function on sunny days although the duration is limited. I suppose it must have a battery somewhere, but it has never been charged.
