ok i'm trying this and measured everything to a T

however when nearly all of the water is evaporated alot of foam happens in the pan and it is a yelowish green color

I NEED HELP PLEASE REPLY IMMEDIATELY

you boiled it to long.

tryed 4 times and no luck...not impressed..i get a caramel smelling sticky sludge

this experiment is a complete fail...and it made my kitchen smell really bad

i screwed up as well, but I am trying it at a lower temp, looks good so far, no where near as messy, if you have a gas stove, turn it down A LOT

this experiment sucks you really know how to fool people.mabey we did somthing wrong but i dont know dude.

is there some1 who really know what there doing cuz my stuff came out brown and it is going to stay out untill is is crystialzed

Most probably boild it to fast and to hot. Slow down take your time you have to stire it all the time almost none stop. I sugest a thicker pot or coile a cloth hanger and place it between the range and your pot so it is not in direct contact with the stove. when you get a white gew or thick foam stop let it cool that will make your "cristals"

all else fails ebay :-) around 15 $ for 1 lbs
and that will make a looooot.

i let the liqued cool in the fridge overnight.
in the morning i had grown long (1.5-2cm) very thin crystals in the bottom. are they pure sodium acetate crystals?
