Today, I noticed some changes in the cups, so I took them out and took individual photos of each. See below.
Styrofoam cup - no changes
Coffee shop cup - dis-colouration, but no decomposing
Biodegradable hot cup - hole at bottom - biodegrading begins
Plastic Cup - no change at all
Plastic Cup - no changes
Biodegradable Plastic Cup - dirt and worms attached in thick clumps cannot see any holes or decomposing of the cup yet.
