Shadow Wifi

Instead of simply informing people of the dangers of UV rays and spending too much time in the sun during the summer months, the Peruvian League Against Cancer and agency Happiness Brussel teamed up to create a “Shadow WiFi” network, that educated people on skin cancer prevention while providing them with free WiFi in the shade.

A large looming blue structure was setup at Playa Agua Dulce in Peru which provided people on the beach with free WiFi access in its shade. A directional antenna ensured that the WiFi was only delivered to the shadow area of the structure. A sensor tracked the movements of the sun throughout the day and changed the rotation of the WiFi antenna. So as the sun moved, so did the shadow along with the WiFi seekers.

Potable Water Generator

UTEC, The University of Engineering and Technology in Peru, believes that engineering can change the world. So they decided to start by changing a local problem and in the process getting more students interested in applying for their engineering program.

Lima is the second largest capital in the world set on a desert, and the lack of potable water is a huge problem. Since the presence of rain is almost zero, UTEC used the atmospheric humidity which is about 98% to build the first billboard that produces drinking water out of air!

Coca-Cola: Wallet of Happiness Honesty Test

An honesty test on a crowded Lima street

As part of an experiment in a very crowded Lima district in Peru, Coca-Cola with their agency McCann Erickson deliberately left a wallet containing $100 on the street. With it they tested people’s honesty.

A $100 question, asked in public

The brilliance is how quickly the situation reads. Find the wallet. Notice the money. Decide what kind of person you want to be, with nobody asking you anything.

In social experiment storytelling, a simple moral trigger creates instant comprehension and invites viewers to project themselves into the decision.

Why you keep watching

You are not just judging strangers. You are quietly measuring yourself against what you hope you would do. That internal comparison is the engine of the film.

What the experiment is trying to reveal

People’s honesty, observed in a real public setting through a simple, high-stakes trigger.

What to borrow

  • Choose a mechanic that is universal and legible without narration.
  • Keep production minimal so human reaction stays central.
  • Let the audience do the interpreting. A good social test creates its own debate.
