In this experiment we used 625L 35% of hydrogen peroxide, which is 3X our last attempt, 245 more liters than Mark and Science Bob’s attempt and 15 times more than Science Bob’s 2018 attempt !!
How we conducted our testing with yeast, potassium iodide, and sodium iodide: 1:3 yeast (saf instant)/ warm water 1L 35% hydrogen peroxide 2 teaspoons soap 140 ml KI (at molar max) 140 ml NaI (at molar max)
For our last attempt we calculated we produced roughly 67.5 cubic meters of foam. We got this through multiplying out previous results and crossed checked this number with a pyramidal volume of 8x8x3 meters (the rough shape of our foam blob).
