Nu ca ma plictisex dar nici nu am nimic mai bun de facut decat sa ma holbez prin pahare si borcane la cocktailurile astora. C\u00e2t s\u0103 \u0219i bei. \u0218i trebuie s\u0103 dau un context pozelor astora, s\u0103 nu zice\u021bi cumva c\u0103 m\u0103 laud, a\u0219a c\u0103 bine a\u021bi venit la ora de chimie. <\/p>\n\n\n\n

\u0218i am dat de o problem\u0103 care creaza paradoxul cocktailurilor. <\/p>\n\n\n\n

Ghea\u021ba. Un cocktail f\u0103r\u0103, b\u0103ut undeva la o calduric\u0103, nu neaparat c\u00e2t s\u0103 transpiri, dar c\u00e2t s\u0103 faci arsuri solare cu tot cu crema SPF 50+, e la fel de bun ca o ciorba, sau ceai. Deci trebuie sa pui \u00een abunden\u021b\u0103, s\u0103 p\u0103streze b\u0103utura rece. Habar nu am, \u00eenc\u0103, de ce fac asta \u0103ia din UK, probabil pentru c\u0103 sunt nesim\u021bi\u021bi. <\/p>\n\n\n\n

\u0218i o dat\u0103 pus\u0103 ghea\u021ba, ai op\u021biunea s\u0103 bei \u00eencet \u0219i s\u0103 te bucuri de temperatur\u0103, caz \u00een care nu te po\u021bi bucura de gust, c\u0103 ghea\u021ba aia se face ap\u0103 \u0219i dilueaz\u0103, fie s\u0103 il bei rapid, caz in care nu te poti bucura de cocktail si oricum ai pus ghea\u021ba degeaba. <\/p>\n\n\n\n

Oricum ar fi, nu e bine. Daca ar fi dup\u0103 mine, a\u0219 inventa ghea\u021ba de cocktail. Fie la pung\u0103, in versiunea pentru s\u0103raci, care e eficient, dar nu prea vrei sa vezi pungi prin cocktail, pe cat posibil. Cred.<\/p>\n\n\n\n

In versiunea pentru bog\u0103tani, ar trebui sa fie un gaz inghe\u021bat, care s\u0103 nu fie toxic si pe c\u00e2t posibil imiscibil in apa\/ lichide. Adica s\u0103 aiv\u0103 at\u00e2t punctul de \u00eenghe\u021b\/solidificare, c\u00e2t \u0219i cel de fierbere sub 0 grade, pe c\u00e2t posibil s\u0103 se evapore din b\u0103utur\u0103 \u00eenainte s\u0103-l dai pe g\u00e2t. Dar nu foarte, foarte mult sub punctul de inghe\u021b al apei \u0219i al alcoolului, c\u0103 nu vrei s\u0103 \u00ee\u021bi faci cocktailul bocn\u0103 \u0219i nici s\u0103 \u00ee\u021bi crape din\u021bii \u0219i s\u0103 \u00ee\u021bi r\u0103m\u00e2n\u0103 limba atarnata pe pahar c\u00e2nd bei. <\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Primul candidat ca temperatur\u0103 e clorul<\/strong>. Se evapor\u0103 prin fierbere la -34C , inghea\u021b\u0103 la -101.5, deci e fezabil doar turnat lichid in bautur\u0103, arat\u0103 super mi\u0219to c\u00e2nd se evapor\u0103, ca un fum galben-verzui , problema cu el e c\u0103 are un caracter puternic reactiv electro-negativ, adica se combin\u0103 cu restul substantelor din pahar, e toxic in forma lui de gaz ( gaz de lupt\u0103) si multe dintre combimatiile in care intra cu alte substan\u021be sunt s\u0103rate \u0219i unele destul de toxice, nu chiar potabile. <\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Urmatorul candidat e butanul, care are un miros fad dar neagreabil, in ingestie nu e neaparat toxic desi actioneaza ca solvent, dar sa il respiri poate deveni, in anumite doze, toxic, nu de ingrijorat. Problema e ca trebuie folosit lichid iar plaja de lichefiere e apropiata de punctul de inghet al apei, altfel e un slab anestezic, misto. Dar e evident ca prezinta riscuri de aprindere \/ explozie, nu prea poti fuma si bea un cocktail, deci n-o sa prinda. La fel e si urmatorul candidat, propanul.<\/p>\n\n\n\n

A\u0219a c\u0103 ajungem unde a ajuns toat\u0103 lumea care s-a mai intrebat asta pana acum. La “dry ice” , CO2, care ingheata la -78C si fiebe la -56C, de fapt nu prea il vezi lichid, se vaporizeaza prin sublimare. <\/p>\n\n\n\n

Nu stiu unde gasesti cocktailuri facute cu cuburi de CO2, dar unde gasiti , incercati ca merita. Bine, nu in UK, la aia nu ai nevoie de gheata deloc. <\/p>\n\n\n\n

M\u0103 rog, ar mai fi un candidat, care cica e un gaz rar, are o faza lichida foarte scurta ( intre -72C si -62C , cand e lipsit de culoare, miros sau gust pentru oameni si se dizolva in ap\u0103) Sub punctul de inghet e galben si daca cobori temperatura cap\u0103t\u0103 accente portocalii ro\u0219iatice. <\/p>\n\n\n\n

Din pacate e \u0219i cam scump s\u0103 aduni destul pentru o pung\u0103 de ghea\u021b\u0103 \u0219i nici nu cred c\u0103 sunt mul\u021bi doritori care s\u0103 vrea s\u0103 \u00eencerce un cocktail cu Radon, <\/strong>lumea \u00eel masoar\u0103 \u00een ppm, fuge de el ca de dracu’ \u0219i se b\u0103nuie\u0219te c\u0103 nu apuci s\u0103 bei prea multe cocktailuri din \u0103stea. <\/p>\n\n\n\n
