This example of our remarkable bubblers "boils" in response to heat from its bulbs, which may be dimmed or brightened as you see fit. It will burble away on its own in an enchanting manner for hours; once the liquid rises to the top after quite some time, simply cup your hand around the top bulb; the heat of your palm will return the liquid to the bottom to burble up again.
