Kalia's hourglass is truly healing itself. The sand piles up much prettier than I thought, and I was amazed that I could control the speed of sand pile up by adjusting the air pressure with a syringe. If you touch it without realizing how much time passes, you can see how to make a pretty desert. I have blue colored sand with a white frame, but I also want black and green. The price range is also good, so I think it would be great as a gift!! Make your own little desert:)
