Extracting Rare Cesium from a Rock

In this video I extract and purify rare and caesium compounds from a mineral I purchased on eBay (pollucite).
I also figured I'd go ahead and demo a few unique reactions that are only possible with caesium, with many more to come in the future!

This video took a whole lot longer than I anticipated to finish, so I hope you all enjoy!
