Observation: 

Metal become thin, and it’s surface area increases.

Explanation:

When we hit metal with a hammer or other hard objects metal spreads into a thin sheet. We call this property of metal Malleability.

Inference/conclusion: This experiment shows that metals are malleable.

Application:

Blacksmith: A blacksmith ( Lohar) heats an iron rod in the furnace and then beats with a hammer until he gets the desired shape.

Steel sheet on the roof is also an application of this property.
