Can a BB gun smash a window?
Considering that airsoft BBs are made from plastic, the weight of a single pellet is therefore negligible, meaning it won't be heavy enough to break a car window upon impact.
weighing 77 grains and traveling at 60 fps will typically cause tempered glass to break (shatter). For normal annealed glass the velocity required is about 1/2 that of tempered glass. 30 fps for the same "object".
Although most BB guns fire low-velocity missiles, some can still shoot to penetrate the abdomen, thorax, facial sinuses and even the cranium. 6-8 A pellet with a velocity of 45 m/s can penetrate human skin and a velocity reaching 60 m/s can fracture bone.
The website Gone Outdoors suggests that pellets are more dangerous than BBs because of the shape and size of the projectiles you're firing. They state that, because they are around twice the size of BBs and because they have an awkward shape, they have a much higher potential for harm than BBs.
BBs flying 100-200 feet per second will only feel like a poke on your skin. Those between 200 and 250 fps will leave you feeling a little pain. Where the shot is from an airsoft gun with BBs moving at 250-300 fps, you'll get a welt from a shot within the 60 feet range. The faster the fps, the more the BBs sting.
Airsoft guns don't have the muzzle velocity or the power to break car windows. While this is mostly due to the use of plastic pellets as bullets, it is also because car windows are made from laminate and tempered glass, making them extra hard to break.
"BB's are a hard steel, so if it shot that glass and cracked it, the BB can end up 100 feet away if it rolls or bounces," Rhoman said. He says if someone is hit by a BB gun it'll most likely leave a welt, nothing more serious. Pellets, on the other hand, can cause more serious damage.
As long as you are over 18, you can possess a BB gun in California. It is NOT considered a Firearm under the Federal definition: "Based on Section 921(a)(3), air guns, because they use compressed air and not an explosive to expel a projectile, do...
The most common caliber of a BB or pellet is 0.177, which equals a 0.177-inch diameter. BB and pellet weights range from 5.1 to 16.1 grains, where 437.5 grains equals 28.35 g. Using the lowest BB weight (5.1 grains or 0.33 g), adult skull penetration can occur at 1025.9 ft/sec.
"Around 350 feet per second is a figure you want to keep in mind," says Beeman. "At 300 to 400 fps, that's where penetration occurs in a human skin. Below 350 fps, it is generally considered capable of only limited harm.
How powerful is a BB gun?
Pellet and BB guns use compressed air to fire projectiles, and are also known as air guns for that reason, though the ammunition used for each is not always interchangeable. BB guns can fire at speeds of up to 550 feet per second. Pellet guns can be even more powerful with speeds approaching 1,000 feet per second.
BB guns can kill a person. High-velocity BB guns, which have muzzle velocities higher than 350 feet per second, can increase this risk. The U.S. Consumer Product Safety Commission has reports of about 4 deaths per year caused by BB guns or pellet rifles.

It will sting a fair amount on bare skin and feel even worse on a finger, or an ear in the cold. However, there are plenty of opportunities to reduce the pain experienced.
In the USA, any child aged ten can already play airsoft, but this is regulated by the state's laws where you live. Some states have a limited minimum age for obtaining airsoft guns.
Next all you have to do is recreate that note, by singing, screaming – or, as O Briain did, using speakers. To smash a glass, you'll need to blast it with upwards of 100 decibels of sound, which is roughly equivalent to a lawn mower. Alas, it won't work with tumblers.
A human voice without amplification, though, will usually fail unless the glass is quite fragile. In 2005, the Discovery Channel television show MythBusters proved that a voice alone could break glass. Rock singer Jamie Vendera shattered a wine glass with a 105-decibel wail.
Breaking the glass will be relatively easy. There is a catch, though. If you use heavy metal to break a glass, you should go around the edge of the glass at its weakest point. Manufacturers assume that in a collision or impact that the center of a windshield or auto glass is the most vulnerable point.
The human threshold for pain comes at about 120 decibels. Highly trained opera singers can sustain notes above 100 decibels. But no matter how loud the sound, if the pitch doesn't match the resonant frequency of the glass, the glass will reflect most of the energy and won't break.
