Pyramids

My father used to have a colour atlas and on one of the pages there was a photograph taken from space which seemed to show 3 bright spots (almost like mirror type reflections) at a point on the earth where the Great Pyramids are located.. Could it be possible that the larger pyramids of Egypt could be viewed from space?

When trains go through tunnels, the windows form an almost perfect mirror and my ears pop. Why?

Is there any way to store light in its raw form? i.e without converting it to electricity and then back into light again.

If I make a box out of mirrors, then open the box in order to to let light in, then I close the box. Why does light not stay stored in the box?

Can you store light in a flask made of mirrors?

My 9 yr old son asked me: if he installed a torch inside a sealed flask made of mirrors and illuminated it briefly, would the light remain in the flask to "flash" out if it were opened. I answered that the light would decay away as mirrors do not reflect all the light and that this would be to quick to measure the decay period - thus, when opened, there would be no light relecting around in the flask. Am I right?
