Modern Day Lava Lamps

I saw something today that I just HAD to say something about. Remember Lava Lamps? Well, what I saw was a modern version of something like it. It looks just like a small version of the classic lava lamp, but it’s powered from a USB port on your computer. Ok, I am not a hamster, I know that a USB port doesn’t have enough power to run anything like a real lava lamp. This is a current of colored glitter flakes in a liquid.
