In this video I follow an obscure synthesis to turn benzaldehyde into a fluorescent dye with a 33-letter name using cool reagents like bromine and UV light while rejecting the sun and becoming a magician by making some very important crystals disappear.

Also, excuse me for my poor speaking, English is not my native language so I have some trouble with pronunciation, in case you don't understand something there are always subtitles made by me.
