from National Geographic:
“A fragrant globe was installed in the new terminal at London Heathrow Airport: just press the sensor with the selected direction and the built-in steam inhaler will disperse the aromas of the five most fragrant and at the same time the most popular in the air British have directions. Bouquet of Thailand is a combination of orchids, coconut, lemongrass and ginger. Brazil is fragrant with tropical rainforest with an admixture of coffee beans, tobacco and jasmine flowers. Japan is the smell of the ocean, algae, amber and green tea. South Africa smells of incense, musk and grass rustling near the Cape of Good Hope. China got the scent of traditional Buddhist temple incense.”
What an awesome idea!
