McDonald’s: Save the Sundae Cone

A melting cone that asks the street to help

Summer is here and McDonald’s is back with an interactive outdoor campaign built around one simple problem. A giant LED billboard in Bukit Bintang, one of Kuala Lumpur’s best-known shopping districts, showcases the iconic Sundae Cone. But it is melting.

To save it, people use their smartphones to spin a fan on the billboard, bring the temperature down, and stop the cone from disappearing.

The mechanic: one shared control, one visible outcome

The execution translates an abstract idea, “cool it down,” into a single piece of viewer control. You open the experience on your phone and spin a fan. The billboard responds in real time. When more people join in, the cooling effect accelerates, so the experience naturally becomes collaborative rather than solo.

In some write-ups, participation is also rewarded with a Sundae Cone e-voucher that arrives on the phone, adding a clean payoff to the play.

In high-footfall retail districts, interactive DOOH, meaning public digital screens that react to what people do, works best when the action is obvious, social, and instantly rewarded.

In high-density urban retail districts, the win is not interactivity by itself but a public action that converts attention into nearby store traffic.

Why it lands

It is instantly legible from a distance. Something is melting. A crowd can fix it. Because the phone gesture maps directly to the visual problem on the screen, people understand the task instantly and the crowd can follow the result without explanation. That clarity creates a low-friction loop: notice. join. watch the shared progress. earn the reward. The “melting” constraint also adds urgency without needing any heavy messaging, and the big screen makes every participant feel like they are influencing something larger than a banner.

Extractable takeaway: If you want people to interact in public, reduce the mechanic to one familiar gesture, make the result visible to everyone, and design the reward so participation feels worth it even for a 30-second engagement.

What McDonald’s is really buying

The real question is whether the screen can turn public play into store-proximate action before attention drifts. This is a strong retail DOOH execution because the interaction, the product promise, and the path to redemption all reinforce each other. This is not only awareness. It is behavior. Get people to take out their phone, do a playful action tied to heat and refreshment, and then convert that attention into a reason to walk into a nearby store. The billboard becomes a live demo of “cool relief,” not a static claim.

What retail teams should borrow

  • Design for crowds first. If spectators cannot immediately understand what participants are doing, participation stalls.
  • Make progress collective. Shared outcomes create social proof and naturally recruit more people.
  • Keep the gesture native. One simple interaction beats a clever multi-step flow in outdoor environments.
  • Tie reward to proximity. If you can convert engagement into a nearby redemption moment, the media becomes a traffic engine.

A few fast answers before you act

What is “Save the Sundae Cone”?

It is an interactive digital out-of-home campaign in Kuala Lumpur where a billboard shows a melting Sundae Cone and invites the public to cool it down using their smartphones.

How do people control the billboard?

They use their phone to spin a fan mechanic that cools the on-screen temperature. More participants increase the effect, making it collaborative.

Why is the melting mechanic effective?

Melting creates urgency that anyone understands, and it turns participation into a visible “save” moment the crowd can watch.

What makes this a strong example of interactive DOOH?

The action is obvious, the feedback is immediate, and the experience becomes social because progress is shared on a large public screen.

What is the key takeaway for other brands?

Use one native gesture, show real-time feedback in public, and reward participation quickly so interaction feels like a fair trade.

Plan: The Erasable Billboard for Girls’ Education

A large illustrated billboard appears in a busy city square. People donate, receive a simple eraser, and start rubbing away the artwork. As the top layer disappears, a second illustration is revealed underneath, shifting the story from girls working to girls going to school.

Plan has reported that tens of millions of girls worldwide are pushed into work instead of education, while in many less privileged countries boys are more likely to get access to schooling. To spark action, Plan and CLM BBDO created an erasable billboard with an illustration designed to be removed to reveal another illustration underneath. The billboard ran in central locations in Paris and Berlin. Passers-by were invited to donate in exchange for an eraser, then use it to change what the billboard showed.

Why the “erasable” mechanic is so strong

The mechanism does two jobs at once. It raises money, and it makes the issue understandable without explanation. The before-and-after is literal. Work disappears. School appears. The donor is not only informed. The donor performs the change. Cause-led campaigns should treat participation as the message, not a bonus layer.

Extractable takeaway: When the donor completes the transformation with their hands, the message becomes a memory and the donation feels consequential.

Definition-tightening: the eraser is not a gimmick. It is the interface, meaning the simple physical tool that gives the donor viewer control over the story. Because the act of erasing creates ownership, it makes someone more likely to donate, talk about it, and remember it.

In social-impact fundraising, participatory outdoor media can turn a small donation into a visible act of change that people feel in their hands.

The real question is whether your donation ask feels like participation or just passive sympathy.

What Plan is really buying

This is a public proof of participation. Instead of asking people to “care” in private, it makes caring visible, social, and shared. Every person who erases becomes a live endorsement that the issue matters enough to stop and act.

Steal this pattern: make giving tactile

  • Make the transformation physical. A tangible before-and-after beats a poster full of statistics.
  • Use the donation as the trigger. The action should only unlock after contribution, not before it.
  • Let participation create the content. The billboard changes because people change it.
  • Design for bystanders. Watching others erase is part of the persuasion.

A few fast answers before you act

What is the “Erasable Billboard” idea?

An illustrated billboard designed to be physically erased. Donors receive an eraser and reveal a second image underneath, shifting the story from girls working to girls going to school.

Why exchange a donation for an eraser?

Because it turns giving into an action. The eraser is a simple reward, but more importantly it is the tool that lets the donor create the transformation themselves.

What makes this more effective than a standard charity billboard?

It is participatory and observable. The public sees the billboard changing in real time, which builds social proof and makes the issue easier to grasp.

What is the main emotional lever?

Viewer control. The donor does not only learn about the problem. The donor performs a symbolic solution in front of others.

What is the biggest execution risk?

If the transformation is not instantly readable, people will not engage. The before-and-after needs to be obvious from a distance and satisfying up close.

MINI: Salutes You in London

In August I wrote about how Coca-Cola Israel used technology to personalise billboards for people who drove by.

Now, as part of its ongoing Not Normal campaign, MINI decides to give MINI drivers in London a custom message by taking over a run of giant billboards along a fast-paced road for a two-week period. “Not Normal” is the positioning line for celebrating owners over product claims.

Reportedly, the campaign reached out to 1,941 MINI drivers in London during the run.

How the billboards “recognise” drivers

The mechanism is deliberately human. Spotters use iPads to identify approaching MINIs and trigger the right creative. Each message is sent with pictures of the make and model of the MINI it relates to, so the driver sees something that feels directed, not generic.

In urban out-of-home advertising, combining live triggers with personalised creative can make a brand message feel like a service moment, not just media.

A human-triggered approach is the right call on a fast road, because it keeps the moment specific without pretending you have perfect recognition tech.

Why this lands on a road, not in a feed

Most personalised media is private and one-to-one. This flips it into a public setting. The driver gets a direct salute, and everyone else sees a brand that appears to be paying attention to its community in real time. That publicness is the multiplier, because it turns a personal moment into shared talk value, meaning people retell it.

Extractable takeaway: Public personalisation works when the proof cue is instantly legible to bystanders, not just meaningful to the target.

What the campaign is really doing for MINI

The work reinforces the Not Normal positioning by celebrating owners rather than pushing product claims. It also turns “existing drivers” into the hero audience, which is a neat way to build loyalty and social proof at the same time.

The real question is whether the salute feels like a genuine community nod, not a clever stunt.

Transferable moves from MINI Salutes You

  • Use a simple trigger and a clear payoff. Recognition plus a tailored line is enough if the timing is perfect.
  • Keep it brand-native. A salute fits a community brand. A hard sell would break the spell.
  • Make personalisation visibly specific. Showing the make and model is the proof cue that prevents it feeling random.
  • Design for safety and readability. Short messages, high contrast, instant comprehension.

A few fast answers before you act

What is “MINI Salutes You” in one line?

A digital out-of-home activation that displays personalised messages to MINI drivers as they pass selected London billboards.

How are the personalised messages triggered?

Human spotters using iPads identify approaching MINIs and trigger the relevant creative, including make and model visuals.

Why use billboards for personalisation?

Because it makes recognition public. The driver feels noticed, and bystanders see a brand visibly celebrating its community.

What do you need to make this work without advanced tech?

A small set of tightly written messages, clear proof cues (like make and model), and a reliable human trigger that can fire the right creative at the right moment.

What is the main transferable lesson?

If you can time a simple personalised moment perfectly, you do not need complex tech to create a campaign people retell.
