Metal packaging, which includes materials like tin, aluminum, and steel, has a long and interesting history with numerous fun facts and anecdotes，These illustrate the rich and often quirky history of metal packaging and its impact on culture, technology, and industry:

1. **Canned Music**: 

The term "Tin Pan Alley" refers to the collection of New York City music publishers and songwriters in the late 19th and early 20th centuries who dominated the popular music of the United States. The nickname is said to have come from the sound of many pianos (which sometimes had poor tone quality and were referred to as "tinnily") resembling the banging of tin pans.

2. **War and Cans**: 

Canned foods played a significant role during wartime. During the Napoleonic Wars, the French government offered a cash prize for a durable food preservation method, which led Nicolas Appert to invent a method for sealing food in glass jars, leading to the development of metal cans.

3. **Beverage Revolution**: 

Metal packaging revolutionized the beverage industry. The first aluminum beer can was introduced by the Krueger Brewing Company in 1935. They initially produced a small batch to see if the beer-drinking public would accept the new packaging, which they did with enthusiasm.

4. **The Can Opener Saga**: 

Early metal cans were so thick that they had to be opened with a hammer and chisel. It wasn't until decades later that the first can opener was invented. The early can opener was a primitive claw-shaped tool which users would thrust into the can to rip the top off.

5. **Rock Bands and Cans**: The British rock band "The Who" featured on their album cover "The Who Sell Out" (1967) a photo of the band members sitting in large Heinz Baked Beans cans, which resulted in Roger Daltrey, one of the members, catching a cold because the beans were cold.

6. **Long-lasting Munchies**: 

The oldest metal can of food was a can of cookies from the 1800s found in the boathouse of the Bertrand, a steamboat that sank in the Missouri River in 1865. When the can was opened in 1974, the cookies inside were still intact and recognizable.

7. **Coincidental Creation**: 

The tin can was invented around 1810 by British merchant Peter Durand, who actually never made a single can himself. He patented the idea and later sold it to two other Englishmen, Bryan Donkin and John Hall, who set up the world's first commercial canning factory.

8. **A Slight Misnomer**:

 Despite the common use of the term "tin cans," most cans are actually made primarily of steel and merely coated with a thin layer of tin to prevent rusting. The tin layer is so thin that it amounts to only about 1% of the total can material by weight.
