Coca-Cola: Happiness Refill

Connection as currency on Copacabana

For teens, happiness often means one thing: staying connected.

Coca-Cola in Brazil acted on this insight by creating a beachfront store on Copacabana Beach in Rio de Janeiro and installing a soda machine that delivered something more valuable than a drink.

Instead of only dispensing Coca-Cola, the machine rewarded users with free mobile internet credits. For young, emerging middle-class consumers who loved their mobile phones but could not afford generous data plans, the exchange was instantly clear and immediately useful.

How the Happiness Refill machine worked

The interaction was deliberately simple. Users accessed the machine through an exclusive Coca-Cola mobile browser. Completing the interaction unlocked internet credits directly on their phones.

No long registration. No delayed reward. Just a physical interface connected to a digital payoff.

The machine functioned as a bridge between the physical and mobile worlds, using hardware as a trigger and mobile connectivity as the reward.

Why free data landed harder than free soda

On a public beach, attention is fleeting. People move quickly, and distractions are constant.

Free data solved a real, present problem. Connectivity was scarce, valuable, and socially visible. Watching someone gain internet access in front of you created instant social proof.

The machine became a gathering point. Not because it was novel technology, but because the value exchange was obvious and human.

The business intent behind Happiness Refill

Coca-Cola’s intent was not short-term sampling.

The goal was to make the brand’s long-standing “happiness” positioning tangible for a mobile-first audience by attaching it to everyday utility. Instead of asking teens to emotionally connect with a message, Coca-Cola embedded itself into a moment of real need.

This activation reframed the brand from advertiser to enabler.

What brands can steal from this activation

  • Translate emotion into utility. Abstract values become powerful when expressed as something people actually need.
  • Design for instant payoff. Immediate rewards outperform persuasion in high-noise environments.
  • Create a public interaction. Physical touchpoints generate social visibility that digital ads cannot buy.
  • Respect economic reality. Value feels bigger when it acknowledges real constraints.

This machine also fits into a broader Coca-Cola pattern. It joins the growing number of Happiness Machines the brand has deployed globally since 2009.

When you make your brand genuinely useful in the moment, people do the distribution for you.

EVOC: The Indestructible Billboard

A backpack is mounted into a bus stop billboard. People step up, throw their hardest punch, and a display instantly shows the force of the hit and how much of it the backpack absorbs.

EVOC wanted to highlight its LITESHIELD protective technology, positioned as shock absorption with everyday wearing comfort. Publicis Munich created a billboard that lets passers-by physically test the backpack’s impact absorption. The unit also ties into Facebook, described as photographing participants and posting the image so they can tag and share their attempt.

The hardest recorded punch is reported as 11.30 kN. Definition-tightening: kN, kilonewton, is a unit of force, so the number is the proof-point for how much impact the demo measured, not a vague “strong” claim.

A product demo disguised as street entertainment

The mechanism is simple. Turn the product into the interface. The billboard does not claim protection, it measures an impact in public and shows both the hit and the absorbed portion in real time.

In performance-driven consumer categories, an outdoor experience that converts a spec into a felt moment can create belief faster than any explanation panel ever will.

Why the Facebook loop matters

The punch is the hook, but the share is the multiplier. By capturing the moment and attaching a score, the activation creates a lightweight competition mechanic, then hands people a reason to post that is about them, not about the brand.

Reported results from coverage include around 97 hits per hour and a 220% increase in Facebook fan activity during the campaign window. Those figures are part of the story because they show what happens when the product truth is both playable and publishable.

What EVOC is really buying

This is credibility and recall. If you let someone try to break your protective promise in public and the product holds, the brand earns a kind of trust that polished messaging struggles to achieve.

What to steal for your next proof-led activation

  • Instrument the claim. If you say “absorbs impact,” measure impact and show the absorbed portion.
  • Make the demo social by default. Photo plus score is a repeatable share trigger.
  • Keep the interaction one-step. No instructions wall. One obvious action, one immediate payoff.
  • Design for bystanders. Watching someone else punch is part of the persuasion.

What is EVOC’s “Indestructible Billboard”?

An interactive bus stop billboard in Berlin that lets people punch an EVOC backpack, then displays the measured force and the absorbed portion as a live product demonstration.

What does LITESHIELD refer to?

EVOC’s protective backpack technology, positioned around impact absorption and back protection while still being wearable for sport use.

Why add Facebook to an outdoor activation?

Because it turns a one-off street moment into shareable content. A photo plus a score gives participants a reason to post and compare attempts.

What does “11.30 kN” mean in plain language?

It is a reported peak force reading from the activation. kN is a unit of force, so the number is meant to quantify the strongest recorded hit.

What is the biggest risk with “proof” stunts like this?

If the measurement is unclear or feels fake, trust collapses. The display must be instantly readable and the interaction must feel authentic.

Lynx: Invisible Ad with polarized glasses

Last month, McDonald’s in Canada created a billboard that could only be seen in the night with car headlights.

Now Lynx, for its “Unleash the chaos” campaign in Australia, replaces the windows of a house in Sydney with special LCD screens. Sexy hostesses stationed outside hand out polarized sunglasses to passersby, and the glasses suddenly unveil the chaos going on inside the house.

In consumer marketing, “invisible” media works best when the reveal is a reward that feels discovered, not delivered.

What makes this an “invisible ad”

An invisible ad is a message that is intentionally hidden in plain sight, then revealed only when the audience meets a condition. Here, the condition is wearing polarized lenses, which gate what the screens are able to show.

The result is a street-level experience that looks ordinary to everyone, but becomes explicit and chaotic for the people who opt in by putting on the glasses.

The mechanism: selective visibility creates instant intrigue

The setup is simple and bold. Take an everyday terrace house. Swap its windows for LCD panels. Hand out sunglasses that make the content readable. Suddenly the street becomes a live demo, with the audience in control of whether they see it.

Coverage of the activation describes it as part of the Lynx Anarchy launch, produced as a filmed stunt to capture reactions and extend reach beyond the street.

Why it lands: it feels like a secret you earned

Outdoor advertising usually broadcasts. This flips the script. The street stays “clean” until you choose to participate, and that choice makes the reveal feel more personal, more exclusive, and more share-worthy.

It also borrows a familiar human impulse. If someone hands you “special glasses”, you want to know what you’re missing without them.

What the brand is buying with this kind of stunt

  • Permissioned attention. People self-select into the experience rather than being interrupted.
  • A built-in talk trigger. The format is easy to explain and retell, even without showing the content.
  • Proof of product personality. The medium embodies the message. Chaos is not only said, it is staged.

What to steal for your next “hidden in plain sight” idea

  • Make the reveal binary. Either you see nothing, or you see everything. Half-reveals feel like malfunctions.
  • Let the audience choose. The opt-in moment (taking the glasses) is what creates commitment.
  • Design for spectators too. Even people who do not opt in should understand that something is happening, and feel curious.
  • Film reactions as a second asset. The live moment is local. The reaction video travels.

A few fast answers before you act

What is a brand “invisible ad”?

It is an ad designed to look blank or ordinary until a specific condition reveals it, such as headlights at night or special glasses in daylight.

What is Lynx doing in the Invisible Ad stunt?

Lynx replaces a house’s windows with screens and hands out polarized sunglasses that reveal hidden content, turning an ordinary street view into a private, chaotic reveal.

Why use polarized sunglasses as the trigger?

Because it creates an opt-in moment. People decide to participate, and that choice makes the reveal feel earned and more memorable.

What is the strategic benefit of hiding the message?

Hiding the message creates curiosity, controls who sees the explicit content, and makes the experience feel like a secret worth sharing.

How do you scale a one-street activation?

By designing it to be filmed, then distributing the reaction footage as the wider campaign asset.
