It was a… it was an urban legend of Gravity Hill somewhere in Pasadena, you would driving to a certain location, I forgot what street it was and you would get off, you would put baby powder on all the windows of the car and you would put the car in reverse and supposedly little kids were pushing you up the hill and then you could see the handprint.
My informant was an active practitioner of this legend. He had heard it from some of his high school friends, however their attempt did not work. He told me this urban legend while we were casually talking about other urban legends. His story reminded me of the same story I had heard about a certain hill in Hacienda Heights, California. The other people that were around us at the time also chimed in, saying that they had seen the same thing in a movie. I have heard several versions of this legend. I heard one version where the heater/air conditioner is supposed to fog up the windows instead of baby powder. I also heard that there is supposed to be a dent on the roof of the car, signaling dangling feet from a hung dead body above.
“For another version of this urban legend, see the movie Fingerprints (2006) based off an urban legend from San Antonio, Texas.
