I thought these were pretty cool. Leave them in the sun during the day to charge up via the solar cell in the lid. At night, the LED light inside lights up and the frosted glass diffuses the light to make them “glow”. Maybe a nice addition to your landscaping?
Or if you are in a part of the world where indoor plumbing is still a dream, these glowing jars could light your path when you answer nature’s call at midnight.
