America Copied Germany’s WWII Jerry Can — But Missed The One Genuis Detail that Made All the Difference

In World War II, Allied armies were losing up to half their fuel before it ever reached the front lines. British flimsies leaked. American jerrycans seeped. But German containers? Nearly perfect.
So why did the U.S. copy Germany’s jerrycan design — and still fail?

This video breaks down the genius engineering behind the 1937 German jerrycan, how American engineers changed one invisible detail that caused massive fuel losses, and how this mistake nearly crippled Allied logistics in North Africa and Europe.
