At work, I have my plastic cheap blinds shut in the orientation of siding on a house. My office is only lit by a lamp. Outside is a sunny day. From my view, directly infront of the window, sitting down, facing north, around mid to late day is of vauge reminisce of clouds in the blue strips of light that gets throught the blinds. - But when I hold my empty plastic water bottle up to my eye, I can see the clouds outside drastically better! I have pictures on my phone of this but don't know how to upload them on here. Anyways, does anyone know whats going on, and why this works? - My observations are that: 1. the orieniation of the water bottle does not effect anything. 2. reversing the blinds the same effect is seen except down low at the cars in the lower half of the window where light gets through that reaches the eyes. 3. Water bottles have slight magnification it appears. - I googled magnification some and I think that is where the answer is.
