Q:

What kind of oil is used in rain lamps?

A:

Quick Answer

Full Answer

When the oil reaches the bottom of the lamp, it fills up a reservoir. The oil in the reservoir is then pumped back up to the storage area, and the oil drips back down again. This recurrent action is done by an electric pump hidden in the reservoir, and the oil travels up through a hose, which is hidden in one of the posts that keep the lamp together.

    Do salt lamps work?

    A:

    Salt crystal lamps emit negative ions into the surrounding atmosphere, which work to neutralize and improve air quality. The salt absorbs water molecules from the air, and releases them when lit. The larger the lamp and the warmer the light, the more negative ions are released into the air.
