To determine which event happened second, let's examine the sequence of events:
- Lee Newman created a special marker pen, but few people bought it.
- Sidney Rosenthal created the Magic Marker, which could write on many surfaces. (This likely happened after Newman's pen was created to address the need for a more versatile writing instrument.)
- The company now known as Crayola bought the Magic Marker brand.
- The company now known as Crayola added neon colors and scents to markers.
Based on this order, the event that happened second is Sidney Rosenthal created the Magic Marker, which could write on many surfaces.
