Claim:
A method of measuring a volume of material, comprising the steps of: providing an adjustable measuring device which includes: a longitudinal outer member; a longitudinal inner member capable of sliding along and rotating an inside wall of the longitudinal outer member; a plurality of measurement positioning stops disposed on the inside wall of the longitudinal outer member, wherein the stops represent a variety of measurement units; wherein the longitudinal inner member includes a peripheral measuring edge projecting from a first peripheral edge of the longitudinal inner member, a peripheral extension member projecting from a second peripheral edge of the longitudinal inner member, and a handle portion for a user to slide the longitudinal inner member along the inside wall and rotate the longitudinal inner member in and out of the stops; and wherein the peripheral extension member engages with the inner wall of the longitudinal outer member and is made of a material firm enough to fit between the stops for measurement and also flexible enough to smoothly slide along and rotate within the inside wall of the longitudinal outer member; filling the material on top of the longitudinal inner member within the inside wall of the longitudinal outer member; moving the longitudinal inner member from the first stop to the second stop along the inside wall of the longitudinal outer member; and rotating and sliding the handle portion of the longitudinal inner member along the inside wall, whereby the volume of the material is measured and moved out of the measuring device.
