Abstract
An apparatus to automatically ignite herbs in a water pipe. The apparatus includes a cap dimensioned to engage a bowl piece of a water pipe and provide a restricted air path to the bowl. A pressure sensor within the cap senses a pressure change response to air being drawn through the air path. Responsive to a signal from the sensor a controller drives an igniter to ignite the herb within the bowl.
