Will a phone book stop a bullet?
A 9mm round shot from a handgun will penetrate three thick phone books. The same round will go through quarter-inch diamond-plate aluminum which is an alloy harder than pure aluminum.
The Panama Police Department in Le Flore County, Okla., fired rounds from various guns into textbooks of varying thicknesses to see if they would stop the bullets. The results, according to KTUL News: Two books stopped a handgun fired at close range, and three stopped a round fired from an AR-15 semiautomatic rifle.

357 magnum, and . 45 caliber rounds. However, the more powerful deer slug shotgun rounds and the M14 rifle were able to pierce the door and the phonebooks easily. Since the phonebooks could not stop all of the bullets, the myth was declared busted.
Kevlar. Perhaps one of the better-known bulletproof materials, Kevlar is a synthetic fiber that's heat resistant and incredibly strong. It's also lightweight, making it a popular choice for wearable bulletproof items. Kevlar is used in both military and civilian applications.
Rickey Wagoner, 49, was shot three times at point-blank range and stabbed in the arm, but survived because both bullets aimed at his chest were stopped by a New Testament devotional Bible in his front pocket, according to WHIO. The third bullet struck him in the leg.
After a test at the shooting range, a regular backpack's front fabric was penetrated by bullets but textbooks stopped rounds from both a 9mm and . 45 ACP from going clear through the backpack.
The guys at Rounds Down Range shot several rounds at brick walls, and brick is surprisingly good at stopping bullets. Brick stopped all handgun rounds plus armor-piercing 5.56 NATO rounds, . 308, and even a shotgun slug.
Unless you've tested this idea, it sounds like it should work. Wrong! I've tested bullet penetration with lots of phone books. A 9mm round shot from a handgun will penetrate three thick phone books.
Level III – Designed to stop a 7.62 x 39 full metal jacket AK round or . 223 ammo like that used by the popular AR-15. This is the minimum needed to stop bullets from any of the major assault rifles. Level IV – This will stop armor piercing roundsand is the highest level of protection you can currently buy.
Women have a higher pain tolerance than men.
Twenty-five members of each gender took part. The women lasted an average of 100.4 seconds in the ice, while the average for the men was 84.3 seconds.
Can sandbags stop bullets?
Sandbags have historically proven to be very effective objects at stopping bullets in their tracks. Used for this purpose since at least around the late-18th century at the Siege of Ninety-Six, they are still widely used today for the very same purpose.
Bullet dodging, Scientific American reports, is one such make-believe ability invented by Hollywood. Regardless of your speed and finesse, no human can dodge a bullet at close range. The bullet is simply traveling too fast. Even the slowest handguns shoot a bullet at 760 miles per hour, SciAm explains.
If you make that foam out of metal, it turns out, it can stop a projectile. Researchers from North Carolina State University have created just such a foam, and it can freeze the trajectory of a . 50 caliber bullet better than the current armor used by the military—thick slabs of steel—at half the weight.
The ability of the polycarbonate layer to stop projectiles with varying energy is directly proportional to its thickness, and bulletproof glass of this design may be up to 3.5 inches thick.

Instead of high-cost Kevlar vests, researchers have discovered that armour made from traditional Thai silk offers similar levels of protection. Tests show that a speeding 9mm bullet can be stopped dead by just 16 thin layers of silk. Use of silk to protect against injury is not a new development.
Unless you've tested this idea, it sounds like it should work. Wrong! I've tested bullet penetration with lots of phone books. A 9mm round shot from a handgun will penetrate three thick phone books.
Diamonds aren't bulletproof, and a bullet can, in fact, break a diamond. That doesn't mean that you should think less of the diamond's fantastic ability to withstand a substantial amount of damage. Remember, diamonds were never intended to stop a force such as the kinetic energy of a bullet.
The metal can make its way into the blood stream and impair the functioning of nerves. “Retained bullet fragments (RBFs) are an infrequently reported, but important, cause of lead toxicity,” the CDC team reports, noting that symptoms “can appear years after suffering a gunshot wound.”
