صباح/مساء الخير للجميع
شاهدت مقطع فيديو عن صنع ثلج في خمس ثواني!!! فياليت اللي عنده خلفية عن هالموضوع وعن المواد المستخدمة فيه إنه يفيدنا... شاهدت المقطع وكان باللغة الـE لذلك ما فهمتها  ((لو نقدر نصنع ثلج بهالسرعة كان ارتحنا من أشياء كثييييييييييييييييييرة)

السلام عليكم طيب هذه الاجابه يمكن تكون اسهل من الفيديو
TRY and get the Sodium Acetate Trihydrate, its about $16 a pound/600grams Photograhy Shops will have it, or just use Google/Shopping.. I picked up the Anhydrous by mistake (sorta), and have found it MUCH harder to get the "ratio" of water to acetate for the supersaturation. . I have been able to make the hot ice, but it was a trial and error process. Get the Trihydrate mixture!  Just boil it untill it starts to bubble, stirring it constantly, adding the Acetate, I started with *about* half as much sodium acetate as to water I used.. and added a little as I stirred it, untill it looked right. I put it in the freezer, fridge should work also, for about 20 minutes.. as I was taking it out, I wasn't careful, and I was Not using a FLAT/CLEAN surface, and it activated.. and started to make the ice like it should. You can reheat this stuff, once you get the right ratios, and just repeat the steps... Its easy folks, just take a chance and heat some water, add the S.A.T., cool it, let it sit to room temp. depending, you can just touch (agitate) it, you can breath on it (sometimes), or simply put just a few "crystals" of the Sodium Acetate on your finger tip and then touching it will guarantee it to activate and start the Icing process.
