McDonald’s: Adult Playland in Sydney

A Playland built for adults, not kids

In order to awaken the inner child in McDonald’s adult consumers, McDonald’s and DDB Sydney built an adult sized Playland in the middle of Sydney.

Supersizing the familiar to make it feel new again

The mechanism is physical and immediate. Take an icon people associate with childhood, then rebuild it at adult scale and put it directly in the path of commuters. It is not a message about fun. It is fun, placed in public, with no explanation required.

In Australian CBD commuter culture, a surprising public installation can interrupt routine and create instant permission to behave differently for a moment.

Why it lands: it removes the awkwardness of “acting like a kid”

Adults do not need to be convinced that play is enjoyable. They need permission. By making the Playland explicitly adult-sized and placing it in the city centre, the brand turns nostalgia into a socially acceptable break from routine.

The business intent: rebuild emotional closeness through participation

This is a reconnection play. Instead of asking adults to remember McDonald’s, it gives them a shared experience they can literally step into, then ties that memory back to the brand.

Since the time of the launch in March, McDonald’s reported that more than 300 people have taken advantage of this playground on a daily basis and engaged with McDonald’s in a way they had not for years.

What to steal if you want adults to engage physically in public

  • Use a recognisable icon. Familiarity lowers the barrier to participation.
  • Change scale to change behaviour. Adult-sizing makes the experience feel legitimate, not childish.
  • Place it where routine is strongest. The contrast is what creates attention and talk value.
  • Make the experience the proof. Participation creates memory faster than any claim can.

A few fast answers before you act

What did McDonald’s build here?

An adult-sized Playland installation in central Sydney, designed to let adults play in a familiar McDonald’s-style playground environment.

What is the core mechanism?

Rebuild a childhood icon at adult scale and place it directly in the path of commuters. The experience is the message, with no explanation required.

Why does it work psychologically?

Adults do not need to be convinced that play is fun. They need permission. Adult-sizing plus public placement makes participation socially acceptable.

What business intent does it serve?

Rebuild emotional closeness through participation. A shared, physical experience creates memory and talk value that a standard campaign claim cannot.

What is the most transferable takeaway?

If you want real engagement, put a recognisable, low-friction action in a high-routine place, and let participation do the persuasion.

Starbucks: Pledge

One person can save trees, together we can save forests! For the good of the planet, Starbucks encouraged everyone to switch from paper cups to reusable travel mugs and get free brewed coffee. So on April 15th thousands of New Yorkers made the switch…

Why this worked as a real-world nudge

The execution is straightforward. Bring a reusable travel mug. Get free brewed coffee. That simple exchange removes excuses and turns a “good intention” into an immediate, rewarding action.

  • Clear incentive. The reward is easy to understand and feels fair.
  • Low friction. The behavior change is small, and the benefit is instant.
  • Social proof at scale. “Thousands of New Yorkers” makes the switch feel normal, not niche.

What to take from it

If you want people to adopt a repeatable habit, design the first step to be obvious and satisfying. The goal is not to lecture. The goal is to make the better choice feel easier in the moment it matters.


A few fast answers before you act

What did Starbucks ask people to do?

Switch from paper cups to reusable travel mugs, with free brewed coffee used as the incentive to prompt the change.

Why does a free coffee mechanic help?

It turns sustainability into an immediate value exchange, which increases participation and makes the first behavior change feel rewarding.

What is the core behavior-change pattern here?

Remove friction, add a clear reward, and make participation visible so people feel part of something larger than themselves.

How does this become more than a one-day stunt?

By making the first switch easy and positive, the campaign increases the chance that the reusable mug becomes the default habit afterwards.
