[QUOTE="westcliffe01, post: 1170543, member: 35183"] Roy, its the old formula F=MA Firing the bullet imparts an impulse to the handgun. Thats the A in the formula. In order for the big mass to start moving it takes time. V = At. You can only see the handgun moving when it reaches a certain velocity and acceleration x time gives you that velocity. The explosive effects have to do with hydraulic shock. After the bullet impacts the liquid, a shock wave will move through the liquid until it reaches the wall of the container, dependent on the speed of sound in the liquid and the distance. When the shock wave reaches the outer surface is usually when the stuff starts flying. The fireball in front of the barrel is the combustion products exiting the barrel after the bullet has passed as the pressure bleeds off. The longer the barrel, the less unburnt products there would usually be. [/QUOTE]
