A water pipe bowl adapter includes a body having an upper end surface, a lower end surface, an outer edge, and a flexible lip that extends downwardly from the body outer edge. There is a through opening extending through each of the upper and lower end surfaces. The lip and lower end recessed portion form a seal for connection with an upper end of a water pipe bowl. When the adapter is arranged on a water pipe bowl, the lip covers an outer surface of an upper portion of the bowl and is secured therewith via a frictional force and the lower end contacts an upper edge of the bowl to connect the adapter with the bowl and create an airtight seal therewith. A user can then place a cigarette in the through opening and smoke through a water pipe with an airtight, secure seal.

A sun-powered smoking pipe with a lens suspended by two arms, whose arms hold the lens at a fixed distance from the pipe's bowl, the distance being equal to the focal length of the lens. The arms have equal lengths and swivel in tandem both at their attachment points to the lens and at their attachment points to the pipe so that the entire device can be folded flat quickly. The only calibration required by a user is to rotate the lens so that the focal point is aimed inside the bowl when the lens is held in the direction of the sun.
