Prigat, a leading company in the Israeli fruit juice market, launched one of the more inventive Facebook mechanics of its era. It invited people to squeeze real orange juice by doing something absurdly simple. Smile at your webcam.
The idea was packaged as “User Generated Orange Juice (UGOJ).” A Facebook application that translated user participation into a physical outcome you could actually watch.
The mechanism: your smile triggers a real machine
A custom Facebook app developed by Publicis E-Dologic used webcam-based smile detection to trigger a real, oversized juicer. When the app detected a smile, it activated the juicer and squeezed fresh oranges. Users could watch the machine live 24/7, so the cause-and-effect was visible rather than implied.
Campaign coverage also described a personalization touch where the participant’s name appeared on the machine during use, and that the resulting juice was directed to a charity choice.
In social platform marketing, physical proof loops outperform abstract engagement prompts because they give people a reason to believe and a reason to share.
Why this lands
This works because it turns a universal emotion into a measurable input. Smiling is effortless, socially contagious, and camera-friendly. The live feed makes the outcome undeniable, and that “I did this” ownership nudges people to recruit friends so their smiles compound into more visible results.
Extractable takeaway: If you want participation at scale, connect a low-friction action to a real-world output that people can witness in the moment, then make sharing feel like extending the impact, not like promoting the brand.
What Prigat is really doing
The campaign turns Facebook from a place for liking into a place for doing. The real question is how to turn a passive social audience into a participant who can see, trust, and share the brand experience. This is stronger than a standard Facebook giveaway because the proof is built into the interaction itself. It converts attention into a visible production line, then uses the live stream as credibility and the smile photos as distribution. Prigat gets warmth by associating the brand with positive emotion and generosity, while the machine supplies a visible proof point that keeps the story believable.
What to steal from the Prigat participation loop
- Design a simple input. The easier the action, the more likely people repeat it and recruit others.
- Show the output live. A real-time feed reduces skepticism and increases share-worthiness.
- Make participation legible. If the user can see their effect immediately, they trust the loop.
- Attach a social good endpoint. A charity destination converts novelty into meaning.
A few fast answers before you act
What is “User Generated Orange Juice” (UGOJ)?
It’s a Facebook app activation where users smile at a webcam and trigger a real juicer that squeezes fresh oranges, visible via a live stream.
How does the smile activation work?
The app uses webcam-based smile detection to decide when to trigger the juicer. The user’s action becomes the on-switch.
Why include a 24/7 live view of the juicer?
It provides proof. People can watch the result of participation, which increases trust and makes the story easier to share.
What kind of results were reported?
Reported results include around 30,000 new likes, over 20,000 photos uploaded, and roughly 40,000 oranges squeezed.
What’s the key risk if you copy this concept?
Trust and privacy perception. You need clear, simple communication that the webcam is used only to detect the smile for the interaction, and that the experience is safe and transparent.
