One tube.
One direction.
One purpose.
The Express Straw System™ is a single, rigid, rectilinear conduit, individually certified to a tortuosity of 1.000. It has a beginning. It has an end. Between them, it has nothing to say.
Engineered to have no features.
Most consumer straws are designed. The Express Straw is derived: from the triangle inequality, the Hagen–Poiseuille relation, and a firm institutional position on loops. Every unit ships with the same specification, because there is only one straight line between two points.
Specifications apply between fixed, unobstructed endpoints. Diameter is “appropriately dimensioned”; questions of radius are outside the scope of our claim of geometric optimality (§5).
| Geometry | Rectilinear, one segment |
|---|---|
| Centerline length L | 200 mm (L = D) |
| Tortuosity τ | 1.000, certified |
| Internal radius r | 3.0 mm — appropriate |
| Priming volume πr²L | 5.65 mL |
| Total turning angle | 0° |
| Radius of curvature Rc | ∞ |
| Dean number De | 0 |
| Loops · helices · hearts | 0 · 0 · 0 |
| Compatible beverages | Coffee, water, carbonated beverages. Milkshakes are non-Newtonian and outside model assumptions. |

Silly Straw Amnesty
Organizations that deploy the Express Straw System™ receive Amnesty Bins for every break room. Employees may surrender decorative straws anonymously, with no questions asked about the heart-shaped one. Surrendered straws are measured, logged and reported to management as Recovered Conduit Length — a figure that, in our experience, managers find deeply satisfying.
Participation is voluntary. Recreational straw curvature is not currently classified as an occupational hazard, and the Express Straw Research Institute has not demonstrated any human productivity benefit from its removal. Whether a looped straw constitutes an organizational productivity concern remains a matter for management.
