Some Mighty Fine 'Shine

What's really in the jug? I'm not sure. Probably just rain water and the compost of 50+ years of leaves and stuff. This log and mud building is around a hundred years old and originally served as a residence. Years later it functioned as sort of a garage / workshop. These items out back of it have likely not been disturbed since the 1940's. The glowing effect was achieved by stuffing my flashlight into the neck of the jug. The fallen log just above it conveniently hid the end of the flashlight.
