What is Digg?114 Comments
- wierdaaron, on 10/10/2007, -10/+74It's not ice, and it's not cold.
It's an exothermic reaction. They make heating compresses out of this stuff. It's poison. You'll die. - Hipple, on 10/10/2007, -2/+31Too bad there's no "Oh *****, this will kill you" bury option.
- MasterInsan0, on 10/10/2007, -0/+18Wow..."video after the break"? I love how people just copy and paste the first words they see from the page into the digg submission and be done with it.
- jerryparid, on 10/10/2007, -0/+17Anything is poison in "large" amounts; you should definitely not ingest this stuff. (Even water, salt, etc)
- zombieball, on 10/10/2007, -0/+14I had a chemistry teacher use this stuff for some "magic tricks". I believe you have to be quite careful that all your cups and pots and pans are quite clean while you make it. The reason it turns solid when you touch it is because the solution just needs some type of impurity to begin crystalization upon. Dropping a grain of sand in the solution will create the same effect.
Cool trick to do with your friends. Pour the white powder in a non-see-through glass before hand. Pour some water into the glass infront of your friend, swirl it around a sec, then pretend to splash the water into the person's face. They will jump! Of course all the water has already turned to a firm jelly which is stuck in the glass (unless you do not put enough powder in, in which case your friend will be covered in a slimey goop. I made that mistake once, oops!) - RSXtacy, on 10/10/2007, -2/+16Alright that was pretty cool... (could have used better music, but i digress)
One Question though is the Sodium Acetate harmful to the human body? - EclipseAgent, on 10/10/2007, -1/+13Wonder how much Acetate is giong to sell after this hits the front page
- ketias, on 10/10/2007, -1/+12From wikipedia:
"Sodium acetate is the chemical that gives salt and vinegar chips their flavour."
so it's probably fairly safe, although it must taste terrible - SpyDerMann, on 10/10/2007, -1/+12OH NO!!! IT'S ICE-IX!!!
- inspecality, on 10/10/2007, -0/+10You're a fun friend.
- sdpdt, on 10/10/2007, -3/+12An aqueous solution of sodium acetate is not *ICE*. Heat flows from the warm finger to the cool solution causing it to change from a liquid to a solid -- just more techie chemistry exploited and explained terribly wrong.
- Nick2632, on 10/10/2007, -0/+9Well I damn sure won't be putting that in my Pepsi
- aedes, on 10/10/2007, -4/+12actually it is ice, it is cold, and it won't kill you. It's basic high school chemistry. btw, the only reason it's exothermic is because the phase change from liquid to solid is exothermic. Pure water freezing into ice is also an exothermic reaction. That's why fruit growers spray their plants with water when it's gonna frost outside.

He's right, this is not ice, nor is it cold. It's really just a transformation from a liquid to a solid (via crystallization). It's hard at first, but then quickly turns into a gel like material. - mogdor, on 10/10/2007, -0/+7Oh the fun I'm going to have fooling my kids into thinking I'm Iceman.........................
- 30thElement, on 10/10/2007, -0/+7no need to buy it, just mix sodium bicarbonate (baking soda) and vinegar. Filter the unreacted stuff out, and boil of a lot of excess water. Only adds about 1 step.
- bigal90, on 10/10/2007, -0/+7i could just imagin your freind with a bunch of goopy ***** all over em
- Sparragus, on 10/10/2007, -1/+6From Wikipedia:
Main hazards: Irritant

Go to number 3. - crapmatic, on 10/10/2007, -0/+5That music is like a band in 1983 opening for a Triumph concert.
- MackPrime, on 10/10/2007, -0/+5keep that stuff away from my scotch.
- Otto, on 10/10/2007, -1/+6Youtube link to same thing, I think: http://www.youtube.com/watch?v=-_Q7FCKZmik
- NicksVideo, on 10/10/2007, -3/+8If he had submitted that URL, maybe he would of realized this is a dupe. And a ***** one at that.
- Harbinger67, on 10/10/2007, -1/+5Clearly, this will usher in a new era in the art of sculpting giant ice penises.
- L4WL3RS34L, on 10/10/2007, -4/+84th time on Digg, and this is definitely supposed to be in the Video section, there's no news or anything. I really hate how people submit it to the News section just for more diggs.
- ilkeryoldas, on 10/10/2007, -0/+3wow, this story makes popular every 20 days.. im not calling this dupe.. just pointing out something interesting

there was another one in the news section but i cant find it using search - bosks, on 10/10/2007, -0/+3What the *****?
- nevesis, on 10/10/2007, -1/+4Seek help.
- smackhero, on 10/10/2007, -1/+3techeblog's "articles" never have any original content (if any content at all). they just stole this off of metacafe and reposted it on their site. stop digging this crap.
- tddk, on 10/10/2007, -1/+3instant as in takes 5 hours to prep for. bury bury bury
and as other said its not ice....burrrrrrrry - sdpdt, on 10/10/2007, -1/+3By the way, this molecule is in the form of a hydrate. Therefore, adding water is a bit redundant, as you can simply heat this beyond it's melting point (approx 100 degrees centigrade) to create the solution. No additional water necessary.
Thank you wikipedia. - aedes, on 10/10/2007, -2/+4not really. use it all the time in the lab. For reference, it's MSDS health level is 1. This is the same value as sucrose (table sugar).
- bIuebonics, on 10/10/2007, -1/+3In America, first you get the sugar, then you get the power, then you get the women.
- bagboyrebel, on 10/10/2007, -1/+3is that a challenge?
- disabled4diggin, on 10/10/2007, -1/+3what does this "after the break" or "after the jump" mean??? i always read that stupid ass line in the middle of some article. was there a point where the article didnt continue? and i had to wait to find out the rest? i dont get it.
- mmykle, on 10/10/2007, -1/+3if u boil the "ice" it will return to its original state. then u can tap it again and it will turn into "ice".
- zweben, on 10/10/2007, -2/+3THE SUGAR!!! IT BURNS!!!
- spucky, on 10/10/2007, -0/+1I don't know why people are digging you down. That looks like a lot of information (for my tiny brain). I always figured that compression would increase heat and decompression would reduce heat. Therefore, the rapid decompression would be the one that would create the ice. Perhaps the compression creates more heat that does not dissipate before the expansion.
Admittedly, I don't fully understand you. But, instead of a glove, we are slamming with a sledge hammer. Could not that cause a little more icefication than a rubber glove? - Moosecapade, on 12/26/2007, -0/+1The sledge hammer coming down would heat up the air, my point is that it quickly cools again since it is an adiabatic process.
- psykiv, on 10/10/2007, -2/+3Start with ice to make ice? Reminds me of that adage. Whats the quickest way to become a millionaire? start as a billionaire.
- Fusco, on 10/10/2007, -0/+1Two main problems with that. First, liquid + thermal energy does not make a solid (in a normal situation - with enough added pressure it would, but that has nothing to do with the energy). Second, a light tap of the finger for less than a second won't add nearly enough "heat" to change something like this substantially.
- bIuebonics, on 10/10/2007, -0/+1all liquids compress. there's a reason they use special hydraulic fluid that compresses far, far less than water. compressed water does NOT turn into ice though; it's actually used in industrial settings for cutting, believe it or now. compressed water spray ftw!
- Burn, on 10/10/2007, -1/+2*Orange Juice
- DeFex, on 10/10/2007, -2/+3how strong is that, and can it be re-melted? might be cool for making molds
- bIuebonics, on 10/10/2007, -0/+1no, compressed water does not come out to be ice. ice is a less dense crystallization of water in which the shape of the water molecules form a specific pattern. you can envision H2O as a V shape with the tops of the V being the hydrogen and the bottom being the oxygen. with the hydrogen slanted off to the sides like that, it creates a non-neutral charge on one side of the oxygen that is overcome at temperatures above 4degrees celsius by the heat motion of the atoms. under 4 degrees celsius the exposed charge on the oxygen atom starts making the molecules restructure their shape until, temperature dropping, it turns to a crystalline form - ice . water is less dense than ice because when its heat temperature is enough to overcome the attraction the V shape of the molecule allows the gaps of the structures to be filled in... well, when you compress water where you'd occasionally have gaps due to various misaligning of the V shape you would get molecules that would press together and condense into more nooks and crannies of the molecules. so basically, no. compressing water does NOT turn it into ice.
- streetr8cer13, on 10/10/2007, -1/+2my chem teacher used this stuff for the water in a glass trick it was funny butsince its exothermic it is not cold, it is warm

aka hot ice - Coded1, on 10/10/2007, -2/+3No beter time to read up on how to take a shower!
- Rekutyn, on 10/10/2007, -1/+2Sounds sketchy to me. Isn't liquid's ability to resist compression what hydraulics rely on?
- Rosy720, on 10/10/2007, -0/+1It's just the conjugate base of Acetic Acid (Vinegar)
- twrife, on 10/10/2007, -5/+6That guy has a lot of milk.
- LtXenodite, on 10/10/2007, -0/+1This same video has been posted lots of times within the past 2 months.
