Mixing The Worlds Most Opposite Elements (Caesium vs Fluorine)

Описание: Subscribe to Prof. Florian Kraus' YouTube Channel: @Fluorineisgreat

In this video we are mixing the worlds most reactive elements caesium metal and fluorine gas, which sit on opposite sides of the periodic table. As you can imagine this turns out to be rather wild. We also went much further using the interhalogen compouns bromine trifluoride and the legendary chlorine trifluoride. For this we were also visited by the great  @NileRed  as well as by  @AdvancedTinkering  who did a lot of great work to make this video possible with the contraption to mix the elements and creating highspeed shots.

Thanks so much to Daniel Markert   / leekgraphy   for helping me out with the thumbnail!

Thanks to everybody working at Prof. Kraus' group who helped with the experiments: To Guliana for preparing the Cs-Metal, to Björn for preparing the liquid fluorine, to Tobias for preparing the bromine trifluoride and chlorine trifluoride and to everybody else there who helped carrying with the experiments in general. It was truly a very nice and welcoming experience!

Additionally thanks to Felix and the University and experimenta of Heilbronn for providing the highspeed camera and helping to create all these beautiful shots!
