Watch Tar Pits Film (2006) : Full Movie Online Free Tar pits form as petroleum seeps to the surface through fissures in the Earth’s crust, leaving viscous asphalt pools. To make Tar Pits Film, Jennifer West threw a strip of film into the La Brea Tar Pits in Los Angeles, still-bubbling asphalt pools which have seeped from the ground for tens of thousands of years. The film was then ridden over hot asphalt by a motorcycle and drenched in other substances including thick mayonnaise and body lotion.
