Magma Lava Lamp

A lava lamp: a flared base and a metallic cap, and in between the column of liquid where the wax slowly rises and falls, never repeating the same shape.

Switched on, it gives a low, coloured light, the kind that changes the feel of a room: in the living room, the bedroom, on a desk or in a playroom. It takes about twenty minutes to get going, then it runs on its own.

A gift people will stare at more than their phone.
