  4. For the first time Night Blooming Jasmine will bloom and spread it's fragrance for 24 hours.
  5. Often when the earth revolves around its axis, a certain part of it receives light from the sun.But for the first time the earth will rotate around its axis without the sunlight falling on any part.

  7. Those trees and plants who slept in the hope that they would cook food in the morning with sunlight, they would not even know that their food has gone missing.
