THE MEAT IS ALREADY ON THE GRILL !!!
THEN, FRIENDS ARRIVE WITH MORE AND MORE STUPIDLY HOT BEER CANS. HOW DO WE COOL THEM?
SCIENCE TO THE RESCUE OF HUMANITY:
PROFESSOR CLAUDIO FURUKAWA, FROM THE INSTITUTE OF PHYSICS OF UNIVERSITY OF SAO PAULO EXPLAINS IT.
PUT THE ICE IN THE COOLER ...
ADD 2 Lts OF WATER FOR EACH ICE BAG
.... ADD 1.1 POUNDS OF SALT
AND 1/2 Lts OF ALCOHOL
WATER INCREASES THE CONTACT SURFACE, SALT REDUCES ICE FUSION TEMPERATURE (IT TAKES MORE TO MELT) AND BY A CHEMICAL REACTION, THE ALCOHOL WITHDRAWS THE HEAT OF THE MIXTURE.
THIS LIQUID IS SOMETIMES CALL "REFRIGERANT MIX" : ICE, ALCOHOL, SALT AND WATER
THE REFRIGERANT MIX IS CHEAP, AND THE BEER IS CHILLED IN ONLY 3 MINUTES.
AND WAITING FOR 3 MINUTES IS NOT A BIG SACRIFICE
I hope you find this post useful , and if you enjoy a cool Beer pls vote the post. Greetings to all.
