makes a nice camping item

I like electricity, and I've heard of the "candle"; I even know about people gathering wood then applying friction; It just occured to me that a reflective thing could make reading or sewing at night possible for people without wood, petroleum, or wires

if this idea had occured earlier those right whales could have just kept swimming right on their way

ancient asian nations could have focused moonlight outside dwellings onto rice paper screens to create an illuminated panel

Thoreau might have have skipped writing about "warms you twice"

more thoughtfully I think this is a good option to create a pleasant resource friendly light among persons whose societies' idea of together hasn't stretched all the way to always on electricity or the wealth to have a crank light

technology: reflective plastic on a wire; concave shape

as an ancient technology: ceramic, or possibly a water sculpture
