Awesome looking relative of the Sun Jar, love the pretty blue glow of this solar powered light. (via Elsewares)

Amazing, eerie and beautiful, this Solar Moon Jar is a great alternative to regular outdoor lighting or night lights. As long as it has a full charge (aka: has been exposed to direct light), the glowing blue light comes on as soon as the sun goes down! Check it out at www.happylosangeles.com! (via happy)

Similar to the Sun Jar - this great blue ball gives the world a blue spin.

I dig this jar light. solar, portable and luminous :)

my son thinks these are magic

First there was the Sun Jar, now there's the Moon Jar! Leave it in the sun all day and at night it casts a lovely iridescent glow. (via Delight Store)

what a wonderful cute idea for home and for a gift that i wont feel bad about giving

I thought owning some moon rock would be fun. Apparently, that's not for sale for $40. Here's the real explanation from www.perpetualkid.com:

Made with a traditional Mason jar and high tech energy efficient lighting! Captured inside the jar are a highly efficient solar cell, rechargeable battery and low energy LED lamps. When the jar is placed in sunlight the solar cell creates an electrical current that charges the battery over a few hours. This energy is then used at night to power the three LED lamps inside the jar.

The light is diffused by the frosted jar and gives the appearance of a ghostly eerie blue glow emitting from inside.
