well, i won't be able to post an accurate yield calculation,  and i feel quite stupid. but i will share nonetheless:

like a fool, i just dumped a bunch of sodium carbonate into the plastic vinegar jug full of acetic caapi and shook it up. i watched the jug start to expand so i quickly opened the lid to relieve the pressure of a significant explosion which happened anyway. the potion came out like a fountain and somehow jumped about 7 feet across the room to land on an exposed heated light bulb, which caused another explosion and almost caused a fire!!! the amount of energy released was truly impressive and surprising. i am sure the spirits had something to do with it because logically it does not seem like so much energy should have been generated from such a reaction.

i should have known better of course. but when working with such mundane things as 5% vinegar and sodium carbonate, i suppose i let the usual safety precautions go out the window.. including eye protection. i am *very* thankful none of the potion made it to my eyes, because it did land in my hair and on my face. i am also thankful that i did not experience an electric fire.

this was truly a humbling experience and i am sharing this with the community so nobody makes the same mistake.
