Fireworks in water drops are really amazing. Some chemical reactions and compounds dissolving in water create a colourful spectacle even in a very confined space like a water drop. The compounds and chemical reactions I selected are: Prussian Blue, Fluorescein, Methylorange and Amylose Iodine.
Prussian Blue, also called Berlin Blue, Parisian Blue, Ferric hexacyanoferrate, Iron(III) ferrocyanide, Iron(III) hexacyanoferrate(II) or Turnbull's Blue, is a blue pigment that can be created by mixing ferrocyanide and iron (III) compounds. The forming nano particles first go into a colloidal dispersion and then precipitate into a heavy paste.
Fluorescein is an organic compound fluorescing in certain blue and ultraviolet wavelengths. In concentrated solutions the its colour appears red but as soon as it is diluted it takes a very intense green colour.
Methylorange is an indicator that is used in labs for titration. It has a equivalence point at around pH 3,1. In the video hydrochloric acid is added to go beyond the equivalence pint causing an intense red colour chance.
Iodine reacts with amylose into a complex that appears blue in colour. Unfortunately the reaction didn't work as intended.
