Waternet Queen’s Day Challenge: Pee Race

Turning a messy problem into a canal-side race

Queen’s Day in Amsterdam brings huge crowds and heavy celebrations. It also brings a very practical problem for Waternet, the city’s water supplier: too many people treat the canals like a public toilet.

Instead of posting warnings, Waternet worked with Achtung! and installed several brightly colored urinals at different points along the canal. Each unit had four stalls and connected to a digital screen that turned peeing into a live race, with a simple incentive that makes people want to participate.

The mechanics that make it work

This is a strong example of ambient behavior-change design. Here “ambient” means the intervention lives in the environment, right where the decision happens, not in a banner ad or a TV spot.

Extractable takeaway: When the right behavior is a public, low-friction default with instant feedback, you can change behavior without asking people to absorb a lecture.

It works because the feedback is immediate, the experience is social by default, and the “right” behavior feels more fun than the “wrong” behavior. That combination reduces friction and replaces shame with competition. This is the kind of public-space activation brands should copy when the goal is behavior change, not sentiment.

In crowded city-center celebrations, playful public interactivity often changes behavior faster than moralizing signage.

Steal the ambient interactivity pattern

The real question is how to make the right behavior feel like the obvious choice in public, without needing anyone to read a sign.

Move the message to the moment. Put the interaction where the behavior happens, not weeks earlier in a campaign feed.
Make the desired action the easiest action. People choose the path that feels obvious and frictionless in public.
Use visible progress. A shared screen and a simple scoreboard create instant social proof.
Reward participation, not perfection. Even a small, symbolic payoff can tip the choice at scale.

A few fast answers before you act

What is the Waternet Queen’s Day Challenge?

It is a Queen’s Day activation in Amsterdam where Waternet installs canal-side urinals and turns their use into a multiplayer race on a connected screen, discouraging people from urinating into the canals.

How does the “pee race” work?

Four stalls connect to a shared screen. Participants use the urinal and the screen visualizes a race, making the act feel like a public, competitive mini-game rather than a private necessity.

Why does this kind of gamification change public behavior?

It replaces a negative instruction (“don’t do this”) with a positive, easy alternative that gives immediate feedback and a social payoff, which is especially effective in crowded, high-energy settings.

What makes an ambient activation succeed in public space?

Clear purpose, low friction, instant comprehension, and feedback people can see without explanation. If it needs a guide, it usually fails on the street.

How can brands use this pattern without relying on shock value?

Keep the mechanism. Swap the provocation. Put the interaction at the point of decision, make progress visible, and attach a small reward to the behavior you want to encourage.

Amnesty International: Sound of Amnesty

This year, charity and human rights organization Amnesty International France turns its signatures petition drive at www.marathondessignatures.com into a musical “hymn to freedom” with Paris-based agency La Chose.

The campaign behaves like a normal petition drive, with one twist: every digital signature releases the next note of an exclusively written song, “The Sound of Amnesty”. To push the idea further, Shazam is used as a distribution channel. When Shazam fails to recognise a song, the app displays a call-to-action message alongside a case story, including: “Valentina Rosendo Cantu could not make herself heard either. Assaulted by soldiers, she asked for justice but the authorities refused to investigate”.

Why the “next note” mechanic works

Most petitions are emotionally important but mechanically flat: sign, share, done. Here, the signature becomes a trigger with immediate feedback. The song becomes a living progress indicator, and every participant can feel they are adding something tangible, not just adding their name to a counter. Because each signature produces an instant, shared “next note” payoff, participation feels consequential, which makes repeat shares and completion more likely.

This is a stronger petition pattern than a static signature counter because it turns support into a felt moment of progress.

Why Shazam is the clever amplifier

Shazam normally appears when you are already paying attention to music. By placing the petition inside the “recognition failed” moment, meaning when the app cannot match a track, the campaign catches people at a point of curiosity and mild frustration. The message reframes that friction as a metaphor for unheard voices, then gives users something concrete to do.

Extractable takeaway: Borrow an existing attention ritual, then use the moment’s friction to make the cause legible and the next action immediate.

In digital petition drives, tying each signature to a shared artifact that literally progresses can turn passive support into collective anticipation.

The real question is whether your petition makes progress feel personal, or just counts people.

Results and escalation

Reportedly, the campaign collected 150,000 signatures, described as a 500% increase from the previous year. The track was also produced on CD and sent to Amnesty’s targeted authorities, turning digital participation into a physical advocacy artifact.

Patterns to copy in petition drives

Give every action an immediate consequence. “You unlocked the next note” beats “thanks for signing”.
Use an existing habit. Hijacking a familiar moment inside a popular app can outperform building a new destination experience.
Make progress audible or visible. A petition counter is abstract. A song evolving over time is memorable.
Connect the mechanic to the meaning. The “not recognised” moment mirrors the core human-rights theme: not being heard.

A few fast answers before you act

What is “The Sound of Amnesty” in one line?

A petition drive where each signature unlocks the next note of an original song, turning advocacy into a progressively revealed “hymn to freedom”.

How is Shazam used in the campaign?

When Shazam cannot recognise a song, it displays an Amnesty message and invitation to sign, using the failure moment as a metaphor for silenced voices.

Why does the “unlock the next note” mechanic increase participation?

It adds instant feedback and a shared sense of progress, making signatures feel like contributions to a collective outcome.

Do you need Shazam to replicate the pattern?

No. The transferable move is to piggyback on an existing user habit and turn an ordinary support action into a small, satisfying reveal that people want to share.

What is the most transferable lesson?

If you want more signatures, do not only ask for support. Turn the act of signing into a small experience people can feel and share.

Slide to Unlock: Audi and Amnesty iAds

Audi “Slide to Unlock”

AlmapBBDO Brazil developed a distinctive iAd for the Brazilian Audi Magazine iPad app. Here, “iAd” refers to an interactive in-app ad unit built for iPad publications. The ad appeared in iPad publications and played with Apple’s familiar “Slide to Unlock” gesture to pull people into the experience.

Users instantly recognised the swipe interaction used to unlock Apple devices. After racing their finger around the track, they were rewarded with a free download of the first Audi Magazine issue from the App Store.

Amnesty International “Slide to Unlock the Truth”

Amnesty International ran an iAd in one of Sweden’s largest newspapers, DN, presenting readers with an image of a prison cell and a prisoner inside. The same “Slide to Unlock” gesture opened the cell and revealed a strong invitation to join Amnesty International as an activist.

Mechanic: borrow muscle memory, then repay it with value

Both executions use the same trick. They take an interaction people already know, then remap it to a brand action. In Audi’s case, the swipe becomes a playful mini-game. In Amnesty’s case, the swipe becomes a literal unlock that reveals a call to action.

In iPad-era rich media placements, the fastest engagement comes from interactions that feel native to the device instead of invented for the ad.

The real question is whether the gesture is already learned, so the first second goes to the message instead of the UI.

This approach is worth using when you can deliver a clear payoff within one gesture and one reveal.

Why it lands

The shared win is immediacy. There is no learning curve. The interface is already familiar, so attention goes straight to the message. Audi uses that familiarity to reduce friction on a content reward. Amnesty uses it to make the metaphor physical and emotionally legible.

Extractable takeaway: If you want interaction inside an ad to feel effortless, borrow a gesture people already trust, then make the outcome either instantly rewarding or instantly meaningful.

What to steal from gesture-first iAds

Start with a native gesture. Familiar interaction reduces drop-off in the first seconds.
Make the mapping obvious. Swipe-to-race and swipe-to-open both explain themselves.
Reward immediately. Audi pays the user back with a free issue. Amnesty pays back with a clear reveal and a direct next step.
Keep the loop short. One gesture, one transformation, one outcome.
Let metaphor do the work. Amnesty’s “unlock” is not decoration. It is the message.

A few fast answers before you act

What is the core idea behind “Slide to Unlock” iAds?

They repurpose a familiar device gesture to trigger a brand action, reducing friction and making interaction feel instinctive.

Why does borrowing a system gesture increase engagement?

Because users already know what to do. That removes instruction time and makes the first interaction feel safe and predictable.

What is the key difference between the Audi and Amnesty uses of the gesture?

Audi uses it for playful interactivity and a content reward. Amnesty uses it as a literal metaphor that reveals a persuasive call to action.

What is the biggest risk when using familiar UI patterns in ads?

If the gesture mapping feels unclear or gimmicky, people feel tricked. The interaction must lead to a payoff that justifies the borrowed familiarity.

What should you measure if you run an interaction-led ad?

Interaction start rate, completion rate, time-to-first-payoff, post-interaction clicks, and whether the interaction improves recall of the message.
