Pepsi Max for its new ‘Unbelievable’ campaign rigged an ordinary bus shelter in London, to perform tricks on unsuspecting travellers.
Using a custom see-through digital display, people waiting at the bus shelter were made to believe that they were actually seeing things like hovering alien ships, a loose tiger, a giant robot with laser beam eyes and so on.
The reactions to these ‘unbelievable’ scenarios were then captured and put in the below viral video.
Why this works. Even before you talk about “tech”
The technology is impressive, but the mechanic is simple. Here, “mechanic” means the repeatable audience interaction pattern, not the underlying tech. It takes an everyday moment. It inserts a believable layer of impossible. Then it lets people do the rest. React, laugh, point, film, share. Because the impossible is framed inside a familiar “window”, disbelief lands fast and reactions become the content. In high-footfall urban out-of-home environments, a brand moment has to work wordlessly, in seconds, for strangers who did not opt in.
Extractable takeaway: If you can turn passive waiting time into a personally witnessed story, you get emotion, proof and distribution before you spend on media.
That is the real move. It transforms passive waiting time into a story that feels personally witnessed.
The bus shelter as a “media product”
This activation treats the bus shelter like a product interface, not just a placement. It has inputs and outputs. Here, “activation” means a physical installation that creates a live brand experience in public space.
- Input. People arrive with low expectations and spare attention.
- System. A “window” that looks like reality, then breaks it in a controlled way.
- Output. Instant emotion, social proof from nearby strangers, and a camera-ready moment.
In other words, it is not only out-of-home. It is an experience designed to be recorded and re-distributed.
The real question is whether your experience turns bystanders into witnesses, and witnesses into voluntary distribution.
What makes it shareable. And why the video is the second product
The live moment is the first product. The viral video is the second product. The second product extends the reach far beyond the street corner.
Tech is optional. If the premise is not instantly legible, it will not travel.
- High signal in seconds. You understand what is happening instantly.
- Escalation. Each new “unbelievable” scene raises the stakes and keeps attention.
- Human faces. The reactions are the content. The brand stays present but not intrusive.
- Social permission. If others are reacting, you react too. Then you share.
What to take from this if you build brand experiences
- Design the moment first. The best “viral videos” start as real-world moments people want to show others.
- Keep the premise instantly legible. If it needs explanation, it loses momentum.
- Make capture a feature. If people will film it, stage it so the footage works.
- Build a repeatable format. One idea, multiple scenarios, consistent payoff.
- Let the audience star. The most believable proof is human reaction, not brand claims.
A few fast answers before you act
What is Pepsi Max “Unbelievable” in one sentence?
It is a London bus shelter activation that used a see-through digital display to create impossible scenes, then turned real public reactions into a viral video.
Is this augmented reality?
It functions like augmented reality for the audience, because it overlays illusions onto what looks like a real street view, even though the experience is delivered through a physical digital screen.
Why do people share this kind of content?
Because it triggers instant emotion and disbelief, and it is easy to explain visually. People share it to pass on the surprise.
What is the key design principle behind the activation?
Make the better story happen in the real world. Then make it easy for the story to travel as video.
What is the practical takeaway for marketers?
When you create a moment that people genuinely want to record, distribution becomes an outcome of the experience, not a separate media plan.
