-found this explanation on lava cooled quickly crystallizes

Probably. Obsidian forms when felsic (silica-rich) magma or lava cools too quickly to crystallize. Mixing it with water would almost certainly do the trick.
Of course, doing so is also going to result in a steam explosion that will shower you in lava/magma, blisteringly hot pieces of stone, probably obsidian shards and almost certainly a large amount of boiling water. And this is not taking into account any hazardous substances that can form from the reaction of water and impurities in the liquid silica sludge.
Also, here’s a fun fact. Did you know that obsidian breaks in a very similar way to things like window glass? You can make ungodly sharp scalpels with it, too. I thought that was interesting, given that producing it with water is likely to turn any formed obsidian into a lot of flying pieces.
