Could you describe what it is ? I never heard of them !

I looked into making these last year when I saw them at the mall. As I recall, you can buy the pumps online, but they start at around $20. The pump does all the work. It mists the water that sits in the vessel. You can use any water-tight vessel you want. A name brand is Mister Frogger. They're supposed to be especially good for you if you have wood heat or an airtight house, because they put moisture back in the air.

I got one for Christmas from my son...I love it! It has changing colored lights, the sound of a fountain, the mist (fog) for adding humidity and also can add scented oil for air freshener! I belive they got mine on ebay...:0)
