Can sound stop a bullet?

A supersonic bullet creates a mini sonic boom – more like a “crack” – which is separate from the sound of the gasses produced at the muzzle, and cannot be quieted by a silencer. This is possible because there is enough pressure behind the bullet, for long enough to accelerate it to that speed.

How close do you have to be to hear a bullet?

How loud is a bullet breaking the sound barrier?

1,100 feet per second
Subsonic bullets and fairly large-caliber war rifles, on the other hand, don’t mix very well. For one, to keep a bullet from breaking the sound barrier – 1,100 feet per second at sea level – requires several trade-offs at higher calibers.

How much sand would it take to stop a bullet?

The theory suggests that about 3 and 1/2 inches of sand would be all that is required to stop a bullet since the standard distance between two pieces of drywall is about 3 and 1/2 inches.

Can plastic stop a speeding bullet?

How much fat would it take to stop a supersonic bullet?

The bullet leaves the Gelatin at about 180m/s. This means that by a very rough approximation you would have to have twice this much fat to have stopped a supersonic bullet. That is 72cm of fat and is somewhat unfeasible, We think that bullet proof vests are probably more practical and probably cheaper!
