Abstract
Certain drinking straw device embodiments comprise an inner tube having a hole along its length and an actuator for actively introducing a gas or fluid through the hole into a liquid flowing through the inner tube. In an embodiment, the actuator stores and releases a pressurized gas. In some embodiments, the actuator stores and releases a second liquid or gel. In some embodiments, a device comprises a non-pressurized gas or fluid substance introduction mechanism, which, when activated, allows the gas or fluid substance to enter and be mixed with a liquid flowing through the inner tube.

- a) an inner tube having a hole along its length;
- and
- b) an actuator for actively introducing a gas or fluid through the hole into a liquid flowing through the inner tube.
A drinking straw device comprising:
- a) an inner tube having a septum wall section;
- b) an outer tube surrounding and sealing the inner tube with the septum to form a closed chamber;
- c) a pressurized gas filling at least part of the chamber;
- and
- d) an actuator for actively introducing the pressurized gas through the slit wall section into a liquid flowing through the inner tube.
