Went to use the bathroom when I saw this.
I hate ants 99.9% of the time because they are annoying as crap when they find food and then there are millions of them making trails throughout the house.
This time though I decided to give them a break. The little guys must be thirsty. These past few months have been very hot. 90+ degree days have been the norm for awhile now. Just like any other creature, water is needed to survive. I guess ants are no different, I've never seen them gathered around water like this before, so I never thought about it till now.
You cannot really see, but the water is suspended in a ring surrounding the drain. I tried to get some close up pictures, I think they came out okay for a 6-year old point and shoot.
