Composition/Division
The Fallacy
Thinking that what is true for one tiny piece must be true for the whole giant thing.
Why it's wrong
If a piece of a puzzle is blue, it doesn't mean the whole puzzle is blue. A car is heavy, but its steering wheel is light.
Example
This brick is very small. So a house made out of these bricks must also be very small.
