Part 3: Show, Don't Tell — Sensory Details
Good writers describe how things look, sound, smell, or feel instead of just stating simple facts.
Example

|---|---|
| The machine blew up. | Sparks flew into the air with a loud crackle as purple smoke filled the laboratory. Warm melted cheese splattered across the clear glass walls, leaving a sticky mess. |
