Tremors (1990)

Audio problem: Right after Bert kills the second graboid he gets on the radio and says "we killed that mother-humper". Val replies "...be advised there are two more mother-humpers". However Val's lips don't seem to be saying "humper". This occurs even in unedited versions of the film. (01:01:40)

Trivia: Reportedly, star Kevin Bacon was at a rough patch in his life during production and didn't understand the appeal of the film or the light-hearted comedic elements. (Even once breaking down in public and exclaiming in frustration "I'm in a movie about giant underground worms!") And thus, he chose to have no involvement in the sequels. It wasn't until some years later that he decided to re-visit the film and give it another chance after it became a massive cult-hit, and discovered that he actually really loved it. Bacon has since gone on record saying one of his dream projects would be to reprise his role of Val McKee in a future film.

Question: Before Burt and Heather are attacked in their basement by the graboid, she puts some bullets and dirt in a machine and turns it on. The machine makes noise and attracts the graboids. What is that machine doing to the bullets and dirt?
