object is at a rate so as to ensure safety of the user taking into account the maximum size of the adjustable compartment so that an impatient user would not experience aspiration by quick release suction movements and or overly rapid repeated suction the above qualifications are preferably achieved by regulating the density of the object preferably the object is denser than water however the object should not be so dense as to fall to the bottom of the compartment too rapidly or so as not to be able to be drawn up to the top of the compartment quickly enough during a suction event appropriate densities typically are between about 1 and about 2 g ml about 1 to about 1 5 g ml about 1 to about 1 2 g ml or about 1 to about 1 1 g ml generally a density only slightly greater than that of water or the liquid being drawn through the straw is preferable generally it is not desirable for the object to float in the liquid as this may result in the compartment being blocked off prior to a sufficient volume of liquid being drawn through the straw it may or may not be preferable for the object to sink in the liquid depending upon whether or not the embodiment contemplates the compartment being sealed at its distal end when no suction force is being applied preferably the object and the compartment can be decoratively shaped or finished to attract consumers particularly children the object may be brightly colored have flecks or speckles of color or glitter be.
