I unfortunately didn't get a picture. There were about 20 of them on the rim of an unopened Coca Cola can in my fridge. I checked the ones not in the fridge and the other cans in the fridge and they were clear, it was just this one can I put in last night before bed. They were not moving so they were at least slightly adhered to the can. They were black and about the size of poppy seeds. I went to clean the can and they fell off just by rinsing it with water. I still washed the can with soap and hot water.

I just can't imagine what they would be. Some sites said moth eggs but the pictures I saw had the eggs very uniform, and these were more scattered but still in the same general location. Artillery fungus was another option, but apparently those are more like spots than balls.

Anyone know?
