The present invention provides a method of making an edible sweet potato composition, comprising: providing a first mixture that includes sweet potato; and forming the edible sweet potato composition, having a mouthfeel in a range of preferably from about 5. The method includes placement of at least two calibrated, differential disturbances or protuberances under the human’s feet. The mount component is mounted on the mount surface. The selection device is configured to direct ink drops ejected from the source through the first nozzle row along a first selected ink drop path and a first non-selected ink drop path. Changing the total length of the baffles can change the affective cross-sectional area of the outlets available for flow at any instant in time. Unlatching structure including a pendulum and lever unlatches the button contact member in the event of a seismic or other event applying a force to the apparatus.
