A couple of days ago I washed the outside of this window, the final wash being with Windex. I've never seen a chain of droplets quite like this, and I call Merikay over. She agrees it's weird, and we watch it for a couple of minutes.
Having always had a better understanding of things we see than I do, she says that water is flowing down through the chain as we watch. From the inside, I can't see enough to agree...
So Merikay goes outside and captures this image:
It shows pretty obviously that she's right, and that water is coming into the chain from above and draining out the bottom.
Have any readers ever seen such a chain of droplets? Can you guess what caused this effect?
