Ecklie: What's going on here?
Grissom: We're trying to determine if a steel-belted truck tire can decapitate a kid driving a go-kart.
Ecklie: I thought that was an urban myth.
Grissom: Myths, legends, tall tales, they all come from something real.
Nick: If that truck was going 60mph, drafting a truck going the same speed, and that truck blows a tire, sending the projectile into the victim's neck and--

Greg: 962 foot pounds of energy.
Grissom: Let's go fellas. (Nick and Greg move over by him, Ecklie is staring at the dummy made out of ballistics gel) C'mon Conrad, there's always room for jello.
Ecklie: That's expensive jello.
Greg: I love this. (Grissom shoots the tire at the dummy, it takes its neck off)
Ecklie: It worked. See if we can't reuse some of that.
