show how a vacuum erection device works?

It works the same way as when you get a hicky. It sucks the blood into your member. When this happens you get hard, causing it to stretch the skin. This allows room for more blood to be able to enter your member! Making it larger!

That's called an erection...\nAnd trust me- it's possible

air would rush into the empty tube and filll the vaccum and some may escape in to space but not very much.\n\nTake a straw and plug the top insert it into a glass of water - remove your finger. if your straw wa almost all the way under you will shoot a little water in the air but the cupp will not empty - physical principles are the same

Good question large man. The reason for this is because when the vacuum is running and you have a little piece of garbage in your hand you can either turn off the vacuum (or leave it running) and walk to the garbage. Or you can stuff a little piece of dirty floor garbage in our pocket, sound nice? Also, people understand intuitively that the reason the vacuum didn't get the string was because it had been worked into the carpet a little, and the vacuum had just made it worse so far, picking it up and putting it down again just undid that, so the vacuum has a good shot now. Personally, i pick up the vacuum nozzle and put the string right in the little hole. If i was a little smarter, i might realize that there is a little opening in the shaft that i could put it in. That's probably what the little opening is for anyway. I don't know. Good follow up question: "What the hell is that little slidey opening on the shaft a of a vacuum for?"

This is not a demonstration per se but there are a series of detailed illustrations that show how a root canal is performed.  I hope this helps...

it is a type of Machinery.

They use toilets that have suction, like a vaccuum does. The guys that go in space have to pee in a hose that has suction and that gets kind of wierd...a guy and a hose.....

The screen is coated with phosphorous and the tube itself is evacuated to form a vacuum.\n\nAn electron beam is produced by a heating element in one end of the tube.\n\nMagnets can focus the electron beam or make the beam spin.\n\nThere are vertical and horizontal plate capacitors in the tube that deflect the electron beam up/down or sideways.\n\nElectrical signals from a TV or computer control the focusing magnet and the charges on the capacitor to produce a picture on your screen.\n\nThis is pretty much a simplistic description of how they work.

buy you a penis pump and use it quite often

you need a pressure vessel, ie gas tank, ISO tank etc. you have to force this in eithermachanically or by vacuum. (not hoover).

well if i am not wrong.. they work on the principle of thermionic emission... \n\nnow wat happens is ... at the cathode end ( negatively charged) there is a metal bit.. called emitter  and at the anode end( positive terminal) another metal called the receiver. the tube is vacuated and filled with gas, in this case a halogen vapour. \n\nwat happens is when a potential is applied, when we switch it on, the cathode emits electrons.\nthese electrons pass thru the vapours and ionise them. when ionised these gases emit energy in the form of light..\n\nthis is the explanation in the most condensed form... equations make it complicated for understanding... \n\nhope i did justice to ur query

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

It's similar to the Venturi Principle, where the jet creates a vacuum effect as it punches a "hole" through the air above the water. Since nature proverbially abhors a vacuum, the surrounding air and the water beneath the hole rush to fill it.\n\nYou can create a similar effect by directing the stream from a compressed air blower between two parallel pieces of streamer material. You would think that the pieces of crepe paper would split away from one another; actually, they tend to come together.

ask a guy to do it for u or use a vacum

Put it under a vacuum.

Is it within a vacuum?\n\nIf not, and if through your above given conditions resulted in air being compressed or what have you then I guess it would.
