The Science of the Beautiful and Deadly Solvated Electrons! (Patreon)

Videos can take wildly different times to make. The work on this one has been going on for at least 3 years! Initially we just had to make a microjet of liquid ammonia, which was a challenge all in itself. Then we had to make it stable in a vacuum and run it for at least half an hour. In the end our run-time record was about 6 hours. Then the real fun started with making the alkali metal-ammonia solutions. These things are fiercely air sensitive, and generally a nightmare to work with. Nonetheless in the end it all worked out and we actually measured the photoelectron spectrum of the alkali metals in liquid ammonia… which ended up on the cover of Science!! 

Not only that…. The supporters of my channel are specifically thanked in the acknowledgements! :-)
