Biosphere Update

Day 76

Day 76
 Our microbe biosphere has continued to remain undisturbed and has shown some more changes.  The black top layer has gotten much thicker and chunky.  The second photo is a truer representation of the color of the dirt--it started out red like clay, and it has now taken on a yellowish/tan color. There seem to be more black spots throughout and some cracks or fissures throughout the dirt.  If you look closely just under the lid of the jar and to the right, there is some bright yellowish/orange growth on the surface of the water that goes almost entirely around the surface (at lease 3/4 around the jar.)  When you shine a light directly on it, it almost takes on a neon color, and it looks like it has tiny fine threads flowing in it, like spider-webs.  The level of the water appears higher, and I'm concerned that it will reach the lid.
