It doesn’t work that way. I was on bottom of 380 feet mineshaft of copper mine that we worked long time ago. Looking straight up I could see blue sky above. But when I look down the shaft from the top of mine I could not any reflection of the sky in the water on the bottom. Just a black hole. I suppose if there was bright star overhead I may see its reflection in water below.
