Brian and Jason make cryogenic fluid by supercooling isopropyl alcohol with dry ice, and are obligated to freeze and shatter things. If for whatever reason you decide to make some psycho soup for yourself, take safety precautions and understand that this is some dangerous stuff. You definitely don't want to consume anything frozen with this stuff, you don't want to be anywhere near touching this stuff, and at the end of the day you probably just don't even want to make it.
