Why does my head not explode when I fill it with compressed air????

It's just like a baloon.

This has happened to me a few times. \n\nThe "thing" loose inside the head is a piece of the epoxy broken off and just rattling around in there. It won't hurt anything, it's just kind of annoying. \n\nBack in the old days I drilled a small hole in the back of my driver and shot some expanding foam in there....that worked then, however I don't think it will work now. \n\nYou can take it to a PGA pro and they can take the head off and shake out your little rascal, but my advice would be to just leave it in there and keep on slappin it!

If it is well controlled, yes.  If not, you are at serious risk for a lung injury.\n\nHere is why.  Asthma is an inflammation of the breathing passages.  This reults in anrrowing and can result in air being trapped (at leats for a short period of time).  At constant pressures, no problem.  But when diving the ambient pressure changes.  \n\nIf you filled a ballon half way full at 30 feet depth, when you surfaced the ballon would be fully inflated.  (The reverse is true as well).  The problem is what if the air inside a trapped space doubles in volume - it has to go somewhere.  Barotrauma is the result.  The ability to equalize these pressure is essential to SCUBA diving -- be it the lungs, inner ear or sinus.\n\nOne other wrinkle: SCUBA can trigger asthma.  Some asthma seems to be initiated by breathing in a bit of salt water (unlikely, but it could happen) or by exercise (like kciking against a current).  \n\nMy advice:  Consult with a doctor familiar with diving physiology. and your clinical history.

it should not deflate so quickly. take it back\nb

I have witnessed this experience several times. I have never had a bag explode open. During takeoff, when the pressure difference between the outside and inside of the aircraft is at its greatest, the bag will deflate. All of the air inside the bag will literally go away. When reaching altitude, and the internal system balances the pressure, the bag will over-inflate. It will become very puffy for a short period of time. When descending, the bag will again become overinflated for a short time, then almost has a weightless feel to it, before becoming deflated once again. When the aircraft is back on the ground and the pressure balances, the bag of chips, provided it was properly sealed and unopened, will look just like any other bag of chips, and they are safe to eat.\n\n* Modern aircraft do utilize pressurized cabins, and while these systems maintain a remarkably steady cabin pressure, they do not always immediately match the ratio needed. This is also why your ears may "pop" when ascending/descending in an aircraft.

What is actually happening is that you are pushing with your neck, and tightening the muscles around the artery traveling to your brain so the oxygen rich blood is not traveling with the typical ease you are used to.  Rather than push with your face and neck, try to push with your butt.   If you fall over or pass out go see a doctor, or if you just want to make sure, however it sounds like what i have just suggested.  Also, don't forget to breathe, its very important.  Eat more fiber.

Fluids are not compressible and since most sea creatures cells/bodies are fluid, they are not affected by the pressure.  Air however is compressible so if the had lungs filled with air, they would have increase the amount of air in the lungs as they dove or get crushed.  Fish with swim bladders have to gradually increase the air in these bladders, if you catch one and reel him up from let's say 200', he is very dead by the time he makes it to the surface as the bladder ruptures as the air expands.

HAHAHAHA You all forgot about our little friend called drag! Inside or out the ball has a drag force acting on it by the surrounding air. Like stated before the air in the car is moving with you, and the car, and the ball all the same and the drag force on the ball at this point is negligible. This is not the effect of a vacume, a vacume is the absence of air. is it possible for there to be no air in the car? NO, Sooo.. outside on a bike or where ever, you are traveling at a speed where the balls light weight will be significantly affected by this drag force and it will cause it to slow down as you throw it up and while you keep riding on un affected by the static(motionless) air, your ball only has one force acting on it, air drag causing it to slow behind you.   test this by throwing a variety of same shaped objects while riding and you will see that the one with the most density will keep up the best. try a marble V.S. a ping pong ball.  then do it in the car

Thre's a fluid that circulates between the brain & the cranium(skull).  The fluid is countinuously produced & drained, thus if there's problem with drainage of fluid, it builds up inside of your head.  The fluid pressure can't go out the cranium, so it exerts force on the brain instead.

use a can of compressed air

Everything is fine.  It is just the changes in pressureas the plain goes up and down.  When the plain is taking off swallow or chew gumm to help them adjust to the lower amounts of pressure, and then when it is landing hold your nose closed and try to breath through it until you feel the pressure change.  don't do it too hard though and stop once the pressure changes in your ears.  Repeat this as necessary.  It can be pretty confusing and weird at first huh?  Nothing is wrong with you though.

I think It's all in the way you move your head honestly turn your head and arms in one direction and the rest of your body will follow but you are right if you do it before you launch it can make you lose some air just cause your body is reacting to to much to soon and try to think about the landing afterwards not just the spin  and of course experiment with how your body reacts to diferent moves until it becomes fluid---well good luck---

No airplane, no matter how well built, is entirely air tight.  A bit of air leaks out slowly through many points and therefore the plane needs a mechanism to keep the pressure up so we can breathe inside.  \n\nThe air pressure inside the airplane is generated by a compressor.  As airplanes get older, the compressors don't work as well and thus take time to adujst the pressure in the cabin, and thus why you can feel the difference in your ears.

it's my understanding that it doesn't really 'explode' - when liquids freeze they generally expand and become hard. since the coke is contained by a can, with part of the top thinner around the tab (due to the scoring), when the liquid starts freezing in some part of the can the remaining liquid is displaced so there is part ice and part liquid. Finally, the remaining liquid freezes, and because there is less room in the can (due to the previous frozen matter, which has taken up more room)there is not sufficient room for all the  material which is trying to freeze - and the can separates at its weakest points. That's why when you open the freezer you may find some contents which have burst out and refrozen once they have'escaped' confinement.

I get this after swimming. I find shaking my head in a fast swooping movement sideways and downwards on the side with water in works. I usually twist my head slightly torwards my opposite shoulder as I reach the bottom. This can take from one to a number of attempts to get it out depending how far in it goes.Sometimes I find too if I tip my head sideways (again on the side with water in) and push the palm of my hand up and down fully across my ear this can sometimes suction it out!  \n\nWhether either of these are medically acceptable I have no idea but after over 25 years as a swimmer it works for me.  Just don't get me locked up for behaing madly!!!

You cant suffocate yourself by holding your breath or putting you hand over your mouth/nose. Your body has a built in survival instinct. However , if you use something over your head you just might suffocate. That is why they put warnings on things such as plastic bags that say they are not a toy.\n\nMessing with breathing is dangerous. At the least if you have no oxygen for several minutes you will suffer brain damage.

There are air tight containers and there are air tight containers.  A birthday party balloon is airtight and ok, an airplane isn't.  Location works the same way.  If you blow up your pop bottle in the middle of a gravel pit, and clean up the mess, probably few people would care.  In someones face would be a different story.  The real worry is what are you going to do next?  \n\nI'd say, in the proper setting, your co2 toy sounds like fun and fairly safe.  Go for it!
