Welcome To
Our Survey.

“Research extends far beyond the confines of a laboratory. We place immense value
on evaluating human experiences and incorporating public perspectives into our work.
Consequently, we host engagement sessions throughout the year to foster active
community participation. Listed below is an example of this initiative, utilizing methods
ranging from surveys to detailed questionnaires. We thank you for your participation
and contribution in this study.”

The “Cap Friction” & Microplastic Study

“Every time a standard PET bottle is opened, the friction between the cap threads and the neck ring creates ‘Shear Stress.’ The Divinity® Research Team hypothesizes that this mechanical grinding is a primary, yet overlooked, source of microplastic generation.

While the water inside may be pure at the factory, the act of unscrewing the cap creates a ‘micro-snow’ of plastic particles that fall directly into the liquid immediately prior to ingestion. This study investigates the correlation between Cap Torque (tightness), Material Brittleness, and the prevalence of visible and microscopic Polymer Fragments on the drinking rim.”

Question 1: What is your gender?



Question 2: What is your age group?






Question 3: What is your country of current residence?
Question 4: What is your ethnicity group?










Other:
Section 20: THE VISUAL AUDIT (The Evidence)
Question 5: When you unscrew a fresh bottle of water/soda, do you ever notice tiny white specks or “plastic dust” on the threads of the bottle neck?



Question 6: The “Safety Ring” Failure: How often does the tamper-evident band (the plastic ring below the cap) break imperfectly, leaving sharp tags or loose plastic strips hanging near your mouth?



Question 7: The “Floating Particle” Scan: Immediately after opening, have you ever seen a particle floating on the surface of the liquid?



Section 30: THE MECHANICAL EXPERIENCE (The Friction)
Question 8: The “Torque” Struggle: How much force is typically required to “crack” the seal of your preferred brand?



Question 9: The Re-Seal Grind: If you refill or re-close the bottle, do you feel the plastic threads “grating” or changing shape (becoming rougher) after multiple uses?


Question 10: The “Cap Deformity”: Does the cap itself warp or change shape when you grip it tightly?


Section 40: THE BEHAVIORAL RESPONSE (The Mistrust)
Question 11: The “Wipe” Habit: Do you instinctively wipe the rim of a bottle with your hand or shirt before drinking?



Question 12: The “Decanter” Preference: Do you prefer to pour the water into a glass rather than drink directly from the plastic neck?


Question 13: Mouthfeel Sensitivity: Have you ever felt a sharp or rough edge on the bottle rim against your lips?


Section 50: THE HYPOTHESIS CHECK
Question 14: Do you believe that the act of unscrewing the cap creates plastic fragments?



Section 60: Additional Information
Question 15: Is there anything else you would like to share/add with us?
