• Short Summary

    Short film explaining how the refrigerator works.

  • Description

    Location unknown.

    A man eating a soup - he blows in direction of spoon to cool the soup as he eats.

    A woman walking towards a refrigerator - 'a new way of cooling things'. She lights the fire at the back of it showing the burner. 'If she wants to cool something, she heats it' - says voiceover.

    Various drawings explaining how the system works. A hand is sprayed with a cologne (as a spirit, it is great absorber of heat), cologne absorbs the heat from hand, spirit evaporates and leaves the hand cold.

    Another diagram shows liquid ammoniac (also a great absorber of heat) evaporating into hydrogen. In order to vaporise, ammoniac absorbs all the heat from its surrounding and leaves it cold. When it evaporates into hydrogen, a fresh supply of ammoniac is needed. A steady supply of ammoniac ensures continuous refrigeration. Combined ammoniac and water, when heated ensures a fresh supply of liquid ammoniac and hydrogen. More diagrams showing the structure of refrigerator.

    Various shots of a man showing the apparatus. Several shots of a waitress opening refrigerator to get cool drink for a customer sitting at one of the tables reading newspaper. She places his drink at the table and leaves. Man takes the glass without looking at it and as he tries to drink his drink, he realises that it is frozen. He turns the glass up side down and his 'drink' falls on the table - a glass shape ice 'sculpture'.
