Ministry of Health Brazil "Sexometer"

They create an urban outdoor, placed in Brasilia, capital of Brazil, to promote condom's use. The idea was to surprise people with a funny and interactive sex thermometer: The "Sexometer". The measuring is very simple. People just have to place their hands at a heat sensor, wich will change color according to body temperature. At the bottom of the outdoor, there is an explanation for each color. If the sensor doesn't change colors, it means your body is still just warm. If it turns blue, it means your body is heating up. Green means you are in the mood for sex. Red means you are on fire and ready to get going. Obviously, all messages led to the same conclusion: use a condom. Thirteen thousand condoms were given at the event.
