what would happen if you cut the metal part of a live lightbulb off?

Since you mean the light bulb is good, then a whoosh of the gas Argon will come out of the bulb.  If you were careful, you could do this without breaking the bulb.\n\nDon't try to do it unless you wear protective eyewear and hand protection!  The bulb is under some pressure; it is not a vacuum.

Well there is a small risk that you could get shocked. I know someone that has damage done to their arm because lighting hit their house and they got shocked through the mouse.

Two- one to change it, the other one to scratch its bottom. :-)\n\nHow many economists does it take to screw in a light bulb?\n\nNone. If the light bulb really needed changing, market forces would have already caused it to happen.

Sounds kind of dangerous, I'm not sure. Depending on how old it is and what type of tv it is, it could be an exploded tube or fried wiring!

Is there a light fixture in place now?\n\nIf not you will need an electrician to install a new box for you.\n\nIf there is already a light that you simply want to replace you can do this yourself.\n\nFirst off find the fuse box or circuit breaker box and turn off the breaker for the light in question.  (Double Check this, It's important.)  Remove the fuse or switch off the breaker and put a piece of tape over it just so it doesn't get turned back on while you're working on it.\n\nNow you will notice that the room where you are working if you have selected the correct fuse or breaker is dark...  You will need a light so you can work.  If you have a helper to hold a flashlight for you it will help.\n\nLight fixtures vary from type to type typically there will be two nuts or screws that hold it to the wall or ceiling.  Remove these two nuts or screws and see if the light fixture becomes loose, note that some lights have been painted over and you may need to score around the light to break it free.\n\nPull the light GENTLY from the wall, you don't want to break the feed wires off and in some older homes the insulation on these wires can be very very brittle.  So be careful (You've been warned!) \n\nYou should see three wires a black a white and a copper wire attaching your old light to the house wiring.  Typically these will be connected with little caps called wire nuts. And they may have black electric tape on top of them. Unscrew the wire nuts and remove the old light, again be gentle with the house wiring, if you break off the wires you will need an electrician to come in and replace the circuit (Again you were warned).  The installation is pretty much the reverse of the removal and instructions should come with your new light.  \n\nThere are many web sites out there to help with this sort of thing.\n\nhttp://www.diynetwork.com/diy/ha_installation/article/0,2037,DIY_13868_2275829,00.html\n\nYou can also check your local library for books.\n\nMost important to remember electricity can kill you and cause a house fire, if you don't know or are unsure about some thing stop and ask a professional or get a professional electrician to do it for you.

What about just unplugging it?

There is a small switch on the side of the fridge that turns the light inside off when the door closes.  It usually looks like a button.

Oh boy.  There's no doubting it when it happens.  Depending on the size they will catch fire and you'll smell a combination of copper and ozone.  It will give out a typical pulse signal however some of the pulses may be missing or it won't produce power at all.

No way, you will get fried if your hit by lightening.

it depends on the size of the bulb, doesn't it?  many different sizes and shapes of bulb..... i'm not sure if there is a size of bulb that every person could 1) fit in their mouth but 2) not remove.  if there is, they should call it the "universally bad idea to stick in your mouth bulb, extra soft lighting 60watt."\n\nanother option would probably be remove the teeth, that would be my guess regarding what's getting in the way.\n\nvery appropriately timed question, as i just replaced two bulbs that had burnt out.\n\nhow many ecluv7's does it take to screw in a lightbulb?  only 1/2, because i do two at once.  :)

yes there is a little switch that gets pressed and it turns the light off

When electricity is given, the bulb glows because of the power dissipated from the tungsten. This is because of the heat produced when current flows through the filament. So when the current is switched off, no current flows through the filament causing the heat not to be created. So the bulb stops glowing and light energy is not given out.\n\nSince no electric energy is given, no light energy is given out. The already produced light energy (before shutting off) i.e. the photons, are absorbed by surrounding objects so that it no longer produces light.\n\nThe photons are the smallest unit of light like cells in biology. Photons have energy in them. These energies are absorbed by surroundings.

Not really. The resulting inny or outy comes about depending on how the end of the umbillical cord dries up and falls off. The way its cut *might have an effect, but its likely to be slim.

They want to be really sure it's out before the go to all the trouble of figuring out how to change it.  Some kinds of fluorescent lights will sometimes come back for a few minutes if you to that, though.\n\n_____\nThe previous answer explains why the would turn it off and then on, but the question asks about on and then off :-P

use a blacK light and see what happens

something really harsh like paint stripper would have an effect as its quie volatile. if you can pour a flammable liquid into the tube such as petrol etc this will light from a distance but be super careful

If its sealed so that water cant reach the electrical circuit, then sure.  Lightbulbs are used underwater all the time for photography and filming.
