why does'nt  a  stand of  hair  burn  when  pulled  tightly  around  a  glass?

I think you are referring to parlor trick where a flame is exposed to a flammable substance which is also in close contact with a container filled with liquid. Where the heat from a flame cannot ignite the hair because the heat is being removed at a faster rate by the cup and liquid then the flame can provide.  A similar experiment is to apply a flame to a paper Dixie cup filled with water, the water will boil away before the heat does any damage to the cup.\n\nThis all has to due with heat exchange rates.   Get a hot enough flame like a blow torch and the hair will ignite.

The electrical contact for the bulb is on the very tip of the screw, and water is kept from reaching it by the screws themselves.  You can tell when you screw it in that it's a tight fit.  Additionally, the glass is sealed to the metal, so that moisture and particulates can't get inside to the filament.

I read a whole book of supposed  instances of spontaneous human combustion, and most of the time it was caused by excess drinking in a hot room or near a fireplace. It kinda makes sense because the amount of alcohol in your blood could cause you to be more flammable. Again, none of this is proven scientifically.

It is because the alchol lamps remain hot for some time even after they are removed from the flame.  So as alcohol is a combustible substance, you are advised not to refill the lamp as they catch fire.

The surface temperature of the glass is lower than that of your hand, thus causing the expansion of the molecules to compensate in order to equalize the surface tension in both the glass and your hand.

mirrors attract ligtning due to their glass. Particles in the glass contain small amouns of parfanenon. This element is conductable with ligtning like water.

Don't try to blow fire out of your mouth unless you want to end up on one of those video shows where people do incredibly stupid things and hurt themeselves really badly. The professionals use grain alcohol, not rubbing alcohol. Try to imagine going through life with half your face burned off before you try this at home.

It doesn't burn like wood. That is, its material does\nnot combine with oxygen as in a conventional burn. Rather,\nthe nuclei of hydrogen and helium atoms fuse under incredibly high heat forming heavier elements. This is the\nkind of nuclear reaction we create in the ignition of a hydrogen bomb. In this case, the high heat is obtained from\na uranium or plutonium atomic bomb which a part of the device.  The fusion results in even more heat, light and radioactive energy.

Your hand does not get burned because it is not over the flame long enough to raise the temperature of your skin and burn you. You are made of water, more than anything else, and it takes time to raise your temp. enough for burning to occur. Now, if it were a very hot flame, like from a welding torch, then it could happen VERY quickly...but a candle flame just isn't hot enough to burn you that quickly.

Glass is non-conductive and was used as an insulator in homes and electric poles.  Since glass is non-conductive, lightning is not attracted to it and will not strike it.\n\nIf lightning could somehow be induced to strike glass, the most likely result would be that the bolt would melt a hole through the glass and continue to something more conductive on the other side.  There is very little chance that the glass would catch fire as silica (the basic material of glass) is not considered to be a flammable material.

Likely happens due to static electricity grabing the hair.  All the rubbing on the front likely creates the force and the weak her likely slips off.

the glass in your galsses is cooler then the air escaping from under the tissue. this will fog the glasses, much like coming in from outside on a cold day

Probably the same reason pulling hair from your head does. Even more so I guess as inside the nose is more sensitive that your head. If you plucked pubic that would hurt for the exact same reason.     :-)  Ouch makes my eyes water thinking about it.

I don't know the specific name for it, but, in telecommunications, there is a certain type of plastic used for insulating wires.  This insulation is known as self extinguishing, in that, as heat is applied to it and it gets to the point where it starts to try to burn, it releases some kind of gas that extinguishes the combustion that is beginning to take place.

because alcohol evaporates the oxygen the fire needs to burn.

I actually did one better. When I was a child, my parents had a very old oven that you had to light with a match. When I was about 14 years old, I opened the door of the oven and struck a match. I got blown half-way across the kitchen. I burned my face and hands as well as having my eyelashes, eyebrows, and bangs torched off.

I would say the thick glass. mainly because My roomate has destroyed many beer mugs making tea.  I would assume the reason is because the temperature is hotter on the inside than the outside  and this causes it to break.
