Spotted this morning at 41 Grand Street in Manhattan: an incredibly dangerous looking homemade slip n' slide! This is apparently part of Recess Art's Wet Slipper installation, where visitors are told they should be prepared to shed their street clothes and don a custom bathing suit "to be reborn riding a log through the flume ride rapids." So if your morning coffee just isn't doing it for you today, head over there for a little adrenaline rush. (The slide will be up through September 2nd... or until the first injury occurs.)
