In this video I grow opals in my parent's garage by experiencing hell with silicon tetrachloride, making TEOS, and playing Sherlock Holmes to find a good procedure for opal production while synthesizing rare tar and having my Dad build me a cute little centrifuge.

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.
