KEZAKO: What is the difference between phosphorescence and fluorescence? 

Dude, that helped me a lot. It was informative and easy to understand .Thanks a lot Keep going 👍😊

Not too bad on the production side. It looks like they may have had some space restrictions or something with their green screen room. Whenever they switch to the full-body shot, visually it looks like she's hunching over. In reality I think she was forced to look _up_ at the camera because they didn't have enough space to back the camera up properly.

Is that you Phoebe?
