can gun-bullets explode in a hot car?  Could the projectile hurt a person, like being shot?

no, they've have to be in a very hot fire. but if that were the case then yes, the projectile could hurt someone, unless they were in wooden boxes then the effects would be confined within the packaging.

Good point! I've seen much worse damage on somebody's face who got shot with a pellet gun!

Yes, as long as the primer and the powder on the inside of the bullet doesn't get wet.  If the projectile is properly set in the casing, then water can't get inside and the bullet will still fire.

Some guy in Australia just invented a gun which fires one million rounds in a minute, or over 15,000 each second (its called Metal Storm and it's nuts).\nTrust me, bullets will be around for a while.

never shooot a gun in the air. a bullet never has a name on it!! i wouldnt even shoot at the ground, it could bounce off a rock or something. stick to targets, much safer!

You have the right idea, but you actually can fire a gun in space. What causes a gun to fire is actually the sudden impulse delivered by the trigger to the gunpowder causing the gun powder to explode, transferring a lot of energy to the bullet and causing it to shoot out of the barrel of the gun. In order to trigger the explosion of the gun powder, you do need an oxidizer to initiate the chemical reaction, but most gun ammunition comes with its own oxidizer built in so therefore, the gun can fire even without oxygen.  \n\nHowever, you shouldn't believe anything physics-related you see in movies,  What's funny is those huge explosions that happen all the time win movies in space with no oxygen like in star wars and armegeddon.  That definately could not happen.  Being a physics major has ruined my appreciation for movies really, I can't watch one without picking out all of the physics mistakes--and there are a LOT, and not just in space movies.  They should employ a physicist to stand by and tell them what they screw up.  Actually, I wish they did, that would be an awesome job haha.

Normally you can't fire a bullet in space. Theres no air to burn with the powder.\n\nAssuming you do though, theres nothing to slow the bullet down, it would travel the same speed as it did on earth, and actually further as there is no friction or gravity to slow it down.

Depends if you play at a range where the guns speeds are regulated (in this case it'll sting but not too bad you'll get bruises as well)  Or if you play with friends in the bush where the guns speeds are above average (this'll hurt like a son of a bitch!  I'm talking huge welts, blood being drawn, and I've been told by the guys there to protect the jewels - I saw a guy bent over for like half an hour puking from that pain!)\n\nAlso always play with a 10 foot rule!!!

Technically, you CAN shoot lightning from your hand, if you get charged with an extremely high static charge. The problem is, you are very likely to get burned in the process. Furthermore, you can't just shoot lightning from point A to point B. Lightning always follows the path of least resistance between two opposite charges. \n\nTherefore, in order to shoot lightning TO someone, you would BOTH have to be charged and with opposite charges, in which case the discharge (lightning) would connect you and him (and you'd both be burned). Alternatively, he would have to the closest object to you so that the lightning would follow the path of least resistance (=shortest) to him.\n\nNaturally, in order to carry such a high charge, you would have to be insulated from everything else, too.

Yes,...or if it hits a tree it can split it down the middle, and should you be in it's path it will kill you more often than not; though, I have read that a few people have been hit more than once and survived; however, their clothing, shoes, etc. were burned.  For the people fortunate enough to have survived a lightening strike,... seems it just wasn't there time to die,...pass on,..meet their maker,...!  Lightening is facinating to watch, but do so from a safe place.  Inside a car is safe because, as you stated, the "rubber" tires provide insulation.\nVery powerful, this thing called lightening!

In English or German, the answer would be the same.  Although the bullet may not cause enough physical damage, there are other things to consider, including site of entry.\nMythbusters never shot a live animal (too much fuss for a publicly viewed TV show).  If they had, they might have answered the question better.  If shot into major artery, the vicitm would probably die of blood loss.  I am not sure of what would happen if shot into the ear or the roof of the mouth.  If the victim lived, it might never be the same.\nUnlike the water bullet, if the blood was the vicitm's, I do not think this could be discovered.  I loved the question.

1. They can be taken away and used by he wrong people.\n2. There are so many people in a small area an innocent person could be shot.\n3. A stray bullet could go through the windshield or plane and cause problems. Well, that might not be possible but certainly if the control panel of the plane was hit with a bullet or two the plane would crash anyway.

It will definitely explode, but not to this extent as you have mentioned. \n\nIf you want a more massive explosion try out a beer can or champagne bottle. Then the blast will be enough to hurt humans, but again not to your desired extent.

Bound's hubby here:\n\nFirst off, how certain are you that the bullets are penetrating the bowling ball and not ricocheting off the round surface of the bowling ball? Second, you should be aware that the core of the bowling ball is almost solid cork, which will absorb more shock than you can dish out. Your bowling ball is really a poor choice in target from a safety stand point.\n\nGood luck.

1.  Aside from the fact that the superhero is, in the first place,  defying the laws of gravity there is one other major flaw in this scenario.  For every action there is an opposite and equal reaction.  The superhero has imparted momentum to the piano and yet we do not see the "opposite and equal reaction".   Perhaps you have seen the true, real life, effect in other movies you may have seen.  Movies in which cannon are being fired.  When the cannon fires it does what?  It recoils.  Armies and Navies for that matter take great pains to control the flight of the cannon upon recoil.  Our superhero seems to be immune to recoil, immune to the conservation of momentum and thereby immune to the laws of physics.  I call "Foul"!\n\n2.  If the truck is at rest when struck by the car, then the car loses KE while the truck gains KE.  If the truck is in motion when struck by the car, in an inelastic collision, meaning the car an truck become entangled and inseparable, then the truck most certainly loses the most KE.  KE= 1/2 * m* v^2.  Velocity (v) is the key here, velocity and it's relationship to momentum (p=m * v; p - momentum). \n\nIn an inelastic collision, conservation of energy is maintained but conservation of KE is not.  (Some of the kenetic energy will be converted to the energy of deformation, sound of the collision)  The Truck will retain most of it's velocity whlie the lower mass car will accelerate largely in what ever direction the truck was headed, most likely causing a net loss of absolute velocity and therefore a loss of kenetic energy for the car.  But the mass of the truck is much larger than the mass of the car.  So the answer to the original question actualy depends on the speed of the truck compared to the speed of the car before the collision.  Why?  Because the collision is inelastic.\n\n"Perfectly elastic collisions are those in which no kinetic energy is lost in the collision. Macroscopic collisions are generally inelastic and do not conserve kinetic energy, though of course the total energy is conserved. The extreme inelastic collision is one in which the colliding objects stick together after the collision, and this case may be analyzed in general terms"\n\n3.  Force and Pressure.   Pressure is simply force exerted over a specified area.  In a car crash, pressure is what kills us and in the case of the airbag, Counter-Force over a wider area is what saves us.  Pounds per square inch, Phyiscs calls that Pressure.  Pressue = Force / Area while Force = M * a^2.  We know that an object in motion tends to stay in motion.  And we know that the law of conservation of momentum guarentees the universe that what is in motion tends to stay in motion and what is at rest tends to stay at rest.  That being said, Force exerted over a given area is called Pressure.  During a collision, a human body has, prior to the collision, a velocity, a mass and therefore a momentum.  And that momentum drives that human being to "stay in motion" even after a collision occurs.  In order to decelerate the body, a force must be imparted.  Enter the airbag.  The airbag inflates.  As the body presses against the airbag, the airbag compresses.  As the air bag compresses and it's overall volume is reduced, the area over which the air pressure acts is less therefore the force / area is more causing a "push back" or Counter-Force affect on the body pressing into it.   Opposite and Equal.  As long as the airbag is strong enough to withstand the surge of pressure (force/area (pounds per sqaure inch)) then the human body will be protected by the absorption of energy that is required to deform the plastic membrane that is the "airbag".  The human frame will be allowed to more slowly decelerate from the collision.  That deceleration will be slow enough to allow the cells and musculature of the human body to maintain its functionality.

Theoritically, everything is possible!!\nIn my openion it might be possible after knowing the chemical compositions of the curry and design a gun accordingly (curry gun). \nBut I don't think it would work as a replecement of the current gun powder becasue you won't get enough gas pressure to propel the bullet.

depends on the gun/cartridge type and how hot it is loaded\nsome well over a mile
