Riding the Film (1937)

The film explains the science of lubrication, particularly in ice skating and machinery. It describes how ice skates glide over a thin film of water created by the pressure of the skate blade melting the ice. The video discusses various lubricants, emphasizing that while water can be used, oil is superior due to its ability to maintain a consistent film under pressure and temperature variations. It details different lubrication methods used in machinery, particularly in automobile engines, highlighting the importance of a continuous flow of oil to prevent friction and wear.
