In English, we often hear people saying "XXX is in limelight"

The literary meaning of "in limelight" is easy to catch, but the science behind of this phrase is rarely clear for most of the English tonges.

Ask you and your friends:

1. What is the science behind this phrase?

2. Any application of this science phenomenon in your everyday's life?

Trust me, it is an enlightening, while challenging, topic for your English speaking friends.

Enjoy
