Goofs and plotholes, just like any other movies
I like this movie but what I noticed after watching again is how the bullet was able to fire and destroy the machine. Yes, I know the bullet hit the Nitrox coolant setting off everything. When a bullet travels through the barrel of a gun, it spins clockwise so it can fly straight because the barrel is designed to do so. Michael strapped the bullet to the side of a rod and it just went off when a it snaps against another rod. It wasn't like the bullet had far to travel to hit the coolant but still a spinning bullet will create greater spin and velocity to create more damage against something as thick as a giant coolant tank. Bullets now are made to shatter when it hits metal anyway so it doesn't bounce back and kill the person firing. Cops have died by their own guns like this until they changed it. But in movies you always see them shoot coolants and propane tanks for some cool action and explosions. Movies like to show bullets on a bulletproof vest on the hero as well. Mythbusters should do something there or did already. I don't watch the show.
