SCIENCE TO THE RESCUE OF HUMANITY:
PROFESSOR CLAUDIO FURUKAWA, FROM THE INSTITUTE OF PHYSICS OF UNIVERSITY OF SAO PAULO EXPLAINS IT.
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
