Solar Bottle Bulb- cheap solar tube for chicken coop


These are excellent improvements on the Solar Bottle Bulb from Liter of Light, using black flashing from Home Depot, roofing tar, duct tape over the cap, and a wire holding the bottle wrapped in aluminum foil as a reflector. Add a bit of bleach to the water to prevent algae from forming.

Can't wait to try it!
