The Social Sweets project was created to test the "Pay it Forward" principle within digital channels. We created a custom Social Sweet chocolate bar to be handed out on the streets of Philadelphia for free. All that we asked in return is that people thank us via Facebook or Twitter. Each time they did a dollar would be donated to Philabundance, a local food bank. After distributing 1000 bars we had some fascinating results, and a city buzzing about our little experiment.
