Flow limiting drinking straw

A fluid flow regulating apparatus, comprising:

• a body having a proximal end in communication with a distal end via an axial passage formed through said body;
• a fluid volume restriction chamber formed in said body, said fluid volume restriction chamber having a volume defined by an upper wall having an annular angled surface, a removable lower wall, and a side wall disposed between said upper wall and said lower wall;
• a first aperture formed at said proximal end;
• a second aperture formed at said distal end, wherein said distal end around said second aperture includes a base wall adjacent to said side wall, wherein the circumference of said base wall is greater than the circumference of said side wall, said base wall being configured to support said apparatus in an upright freestanding position, adapted for creating a sealed engagement to a drinking straw;
• and
• a sealing member having a circumferential surface sized for translation inside said fluid volume restriction chamber between said upper wall and said removable lower wall of said fluid volume restriction chamber;
• wherein said sealing member is movable between a seated position blocking communication of said first aperture with said axial passage and a second position allowing communication of said first aperture with said axial passage.
