Turning hot air into artistic fresh air

Joshua Allen Harris is turning subway hot air into artistic fresh air.

The New York art student creates plastic animals out of garbage bags and attaches them to sidewalk subway grates.

The animals inflate when a train passes. It's like that scene in the classic Marilyn Monroe movie "The Seven Year Itch."

Her skirt flies up as she's standing on a subway air vent.

Harris says the best part of his project is the reaction of usually jaded New Yorkers.
