As it is a amusing of chemistry . After cooling the coka , the extremely low temperature decreases the kinetic energy in the system ( coke）very much. Then shaking the bottle and immediate open it , then close , it makes the high pressure coming out , however the high pressure is closed in the bottle and makes the pressure in the system up suddenly . The high pressure makes the water molecules to pack close much together , as at this time , a attraction force called " H - bond" bonds the water molcules to form solid ice , but it is essential that that attraction force is higher than that of the kinetic energy in the system . As the essential factor ( attraction force is higher than that of the kinetic energy in the system ) is built in this case as the kinetic energy is too low . Therefore, coke can form ice under this situation.
