This volcano is similar to the lava lamps that you plug into any wall outlet for power, with the exception that this one is USB based. As such, power for this desktop gadget is from the pc or laptop. This makes it more portable, adds a touch of uniqueness to your work environment and of course, when you need to take a break, just lean the seat back and watch the lava churn and bubble. Oh so soothing. Must be great for the blood pressure.
