get yourself a big bowl and fill it up with Ice and rocksalt and water and then agitate it. then soak you hand till it feels like its gonna fall off, then let it warm back up, then freeze it agin. and so on. Just becareful not to over freeze and give yourself frostbite. also if you take styrofoam cups and fill em half full with water then freeze em and peel the cup down so the ice is exposed and rub that on there. that technique works well and keeps the working hand from gettin cold. If your fingers are gonna be numb best be from the cold not the cut off circulation pressure on the nerves. Hope that thing gets to feelin better. i hit a tree a few weeks ago and racked my thumb and jambed my wrist and they still hurt. [img]i/expressions/face-icon-small-sad.gif[/img]

 

What does the rocksalt do?

 

Lowers the freezing point of the water and it also causes the water to get colder when agitated with the ice. even the salinity of ocean waters allows the water to be chilled to 28 or 29 without it freezing. We did an experiment on one of our boats for the Jap fish buyers and we addeda couple thousand lbs of salt to the fishhold and chilled the water to 24° to see if the quality of the fish was anybetter when we got em to the plant. It ended up bein to much of a pain. The Chillers kept Icing up and it was hard on the compressors. anyway It just gets colder. Colder beer put Ice in a bucket with rocksalt and water. Open your beer and it turns to ice. ever made icecream? you put rocksalt and Ice on the outside of the Stirtub because it gets coooold. anyhow. lol[img]i/expressions/face-icon-small-smile.gif[/img]

 

94.1 g must be added to 1 kg of water to Lower the freezing point -6°C.
The agitation causes the molicules to get pissed off and the get cold. [img]i/expressions/face-icon-small-wink.gif[/img]




Some Basic Chemistry Concepts for Solutions

 

Ok By my calculations 11 oz NaCl (salt) added to 1 gallon water allows it to be chilled to -6°C or 21°F
The typical salinity of sea water is about 3.7 ounces per gallon so one could duduce that to be roughly 1/3rd the salinity of the control solution. that being said seawater should be a freezing point of -2°C or 28.4°F

How do i get my numbers?
Distilled water weighs in around 62.4 lbs/Cu.ft
Sea water weight iin around 64.1 lbs/Cu.ft
there are 7.48 Gallons in a Cu.ft
So Pure water weighs around 8.34 lbs/gal
and sea water weighs around 8.57 lbs/gal
and blah blah blah ... [img]i/expressions/face-icon-small-wink.gif[/img]

Well looks like i gonna be puttin in a lil overtime tonight. DAMMIT!!![img]i/expressions/face-icon-small-mad.gif[/img] What a bunch of crap. I will be here till at least 9pm. so sad [img]i/expressions/face-icon-small-sad.gif[/img] you been pickin on me allot JIMBO you gonna make me come out to hillbillyvilla and..... give ya a beer [img]i/expressions/face-icon-small-wink.gif[/img]

 

You got Ruski's workin' for you too?
