Review on Liven Up Your Space with the Jellyfish Lava Lamp – 16 Color Changing Lights, Aquarium-Style Jellyfish Tank Night Light, Ideal Gift for Both Adults and Kids! by Jamie Miller

Bought this for my son instead of real fish and couldn't be happier! You are so alive! Just fill with water and put in. Turn it on and they will keep moving randomly. If some seem to stagnate, there's a small poker stick. The controls are great so my kids can dim the brightness or change the color to go to sleep. There are about 12 color settings and about 4 transition settings (fade, strobe, etc.). So many people thought they were real! I'm half tempted to get another one! Do not be shy! This is the BEST invention ever!
