Yes this works, but does anyone know how to get the f@#&ing glass bottle off my hand

I did! If the splinter sits not too deep, it works great :)

A neighbor did this to me when I was a kid and it worked better than mom and a needle

I actually already knew about this. Works like a charm ;)

It's rather just after being boiled. I once saw a florist working at church flowers. She did this to sunflowers with a water that has just been boiling.

The same temperature as the boiling blood in your veins after being the lone survivor of a drastic war, bordering the land of overflowing volcanoes.

Likely just at too hot to touch

I was wondering that too.. Right after I boiled it or what? Wouldn't that be cooking the flower? =X

like megan fox in the transformers

Hand hot.

Typically hot water is steaming but not simmering; I would venture to guess that they mean no hotter than your tap produces.

Hot: warmer then cold. Boom. Word defined.

Lukewarm

boiling hot

I once killed a sapling with luke-warm water, so I am not trying this..

It's a North American fish that is sadly extinct. It weighed in excess of 300lbs and was known to sing on moonlit nights.

Never heard of sal ammoniac...also quite happy I can purchase a fire extinguisher. But when in doubt, if electrical or a grease fire, my mom always taught me to either cover the flame or throw baking soda or salt on it. I see why: "Sal ammoniac is also the archaic name for the chemical compound ammonium chloride. The Romans called the ammonium chloride deposits that they collected from near the Temple of Jupiter Amun in ancient Libya 'sal ammoniacus' (salt of Amun) because of proximity to the nearby temple.Salts of ammonia have been known from very early times;.... In any case, that salt ultimately gave ammonia and ammonium compounds their name. It is commonly used to clean the soldering iron in the soldering of stained-glass windows. In both jewellery-making and the refining of precious metals, potassium carbonate is added to gold and silver in a borax-coated crucible to purify iron or steel filings that may have contaminated the scrap. It used to be used in baking." (Per Wikipedia)

Some countries its known as ALUM easily available online. Excellent for blood clot in case of a cut from shaving or anything else.

It is a mineral salt form of ammonium chloride commonly used as a soldering flux.

It's also called salmiak in scandinavian countries, they use it as an ingredient in salted liquorice.

It's a mineral. These days, it's mostly used in block form for tinning soldering irons. It used to be used in cookies to make them crisp (it might be used in some countries still).

Why... The liquid extracted from salmon left to go rancid for a month in your fridge of course...

actually that should be....WHAT THE HELL IS SAL-AMONIAC??????

Isn't that the Jewish guy that runs the Deli?
