geological cocktails

I... do not entirely recall how we got onto this topic, but a conversation I had with a friend earlier led me to discover the Flaming Volcano", a cocktail that appears to exist more for the sake of the dramatic visuals than anything else.

Everything else I could find already attested was a bit of a disappointment, alas (e.g. this Buzzfeed listicle that doesn't even include pictures of the drinks).

Given the existence of volcanic bombs and lava fountains I sort of feel like there's scope for a lot more creativity here!
