Friction is not just slipperiness. It is the force that resists sliding when two surfaces meet, and its strength depends on how hard surfaces press together and how “grippy” the contact is between them. Metal on metal grabs differently than metal on glass because of what happens at a microscopic level. Iron and steel are ductile, meaning their tiny surface bumps can flatten and even micro-weld together under pressure, creating strong adhesion and generating intense heat. Glass is brittle, so instead of deforming and bonding, it chips and cracks when metal slides across it. This is why side by side tests look so dramatic. Iron on iron can gall, smear, and in extreme cases approach friction welding conditions with visible heat. Iron on glass tends to score and fracture the surface instead, producing a completely different damage pattern. The difference is not just a number on a friction scale but a reflection of how each material responds to stress at the contact point.

@autopoiesis.scienceWatching it in its original place is always the most accurate source.
A multiplier needs two things: a trustworthy publish date and a duration. At least one is missing on this record (on Instagram the publish date is often just the collection time) — so we are not making a multiplier up.

All of it comes from the API. If a value is missing you see a dash — nothing is estimated in its place.
📈 Growth history
The real view record that builds up as we measure the video again and again.
Only a small share of the videos in our pool have more than one real measurement. This one was measured once (or always at the same value) — rather than drawing a meaningless flat line, we say so.

Open this video with AI
The numbers above tell you how well the video is doing. The AI Lab looks inside it: it reads the opening frame, the edit and the sound, and answers “how would you do this”.
- Hook score (0–10) and why it stops the scroll
- First 3 seconds — opening frame and composition
- Why it went viral — one clear answer
- Edit / structure — how the video is built
- Target audience + music/sound strategy
- Actionable recipe — step by step, how you catch it
