In a move that would make documentarian Morgan Spurlock start a vigorous slow clap, several Big Fuel New York staffers will attempt to live below the extreme poverty line for five days. Starting on Monday, May 7, Big Fuel managing director Holly Pavilka and several of her co-workers will be spending no more than $1.50 a day. The bottom line? No coffee (shudder).

The agency peeps are taking part in this social experiment as part of the “Live Below the Line” challenge, a charitable contest that has thus far raised over $44,000 for poverty-stricken citizens in developing countries. “Live Below the Line” is being co-sponsored by Unicef, the Global Poverty Project, and the United Nations Foundation’s Shot@Life initiative. According to a statement, Pavilka and co. are also using this challenge as a way to bring attention to social media’s impact on raising awareness for charitable initiatives.
