In the scene where Marty tries to scare George into asking Loraine to the dance by dressing up as a space man from the planet "Vulcan", you'll notice that Marty has a hair dryer tucked in his belt, but when the camera cuts away then back to Marty, you'll see that the hair dryer is gone...It switches back and forth a few times. This also brings up another question, "How did Marty get a hair dryer? because in 1955, there were no hair dryers." Well, the answer is simple. There was a scene that was cut out that shows Doc packing a suit case with items he may need if he traveled through time. Doc, in 1955, looks at the hair dryer and says "What's this contraption?" Marty replies, "It's a hair dryer", Doc snips "Why would someone need a hair dryer? Aren't there towels in the future?" The proof to this is on the video "Secrets of the Back To The Future Trilogy"
