So my kids science teacher was doing some "things that aren't real in movies"
like lasers in starwars wouldn't have the sounds since its a vacuum, this I can get behind But when he talks about the scene in back to the future where the massive speaker knocks alex p Keaton backward I have to take umbrage. I always equated the pressure waves from speakers with the soundwaves, but since realized its the motion over the speaker creating a pressure wave. But now I'm reading a sound wave itself cant do much to move an object. This is just bothering me next somebody is going to tell me that the quarters under my pillow after I have a tooth pulled are just magically appearing there and there is no tooth fairy (yeah right)
