First-of-its-kind “Science City Explorers” Snapchat Lens reveals science and technology behind NYC’s infrastructure, ranging from fire hydrants to stop signs.

This new educational Snapchat Lens uses machine learning to recognize common objects from New York City’s infrastructure. By unlocking the Lens and pointing the Snapchat camera at selected water, electricity and transportation infrastructure across the city, Science City Explorers reveal the behind-the-scenes technology powering NYC. For instance, Snapchatters can scan a stop sign; the Science City Explorers Lens will recognize the object using machine learning and reveal a hidden science component that powers it – in this case, the reflective sheeting that increases visibility and luminosity at night.
