"Lights" made from soda bottles
 

What an interesting concept. 2 liter soda bottles filled with water and fit into the roof in a way that lights the room below.

Very creative and they really seem to work well.

That's cool!

Last camping trip Andrew's wonderful wife did something similar to good camp lighting effect by balancing a gallon water bottle on top of a flashlight.

That's awesome! I've thought about getting this solar light cap for use camping. It turns a normal Nalgene-style water bottle into a light.

From a YouTube commenter:

"We have a similar invention, it's called a window"

Ahhh haaa haa haaahhhhh!!! :D

I gave poor badgershroom a thumb's up, as his comment has taken a few hits. Nobody appreciates a wise-ass.

This is great, if you don't have an attic space, or insulation, or anything.

Perhaps I'd remember this trick for a playhouse or a shed of some kind.
