West-en, thanks a lot, this seems quite understandable, but then probably swim has to expect as well some water appearing (when the bicarbonate breaks into carbon dioxide and water), or maybe due to the heat it will evaporate together with the CO2. It is nice that you have put down a formula, it makes it even more understandable. Do you know what is the chemical process that happens behind the "washing" of elves spice + nafta/rubber cement remover + NaOH (the lye)+ Na2CO3 (the soda), swim was wondering how exactly the NaOH is washed away?
