create the best household cleaner! mix bleach and ammonia!
yes, some people did this, and summarily passed out from the toxic fumes.
As for the sodium iodide + Hydrogen Peroxide reaction, i really have no idea... gimme a sec...
NaI + H2O2 > NaOH + IOH
so, sodium hydroxide and iodine hydroxide, if my sub-standard chemistry skills are on the bat. its either that or sodium oxide and hydrogen iodide, or sodium iodide and hydrogen oxide (or dihydrogen oxide, i couldnt get the specifics, i assumed the H2O2 decayed into hydroxyde radicals first).
oh, BTW: its the Hydrogen peroxide thats the oxidiser, not sodium iodide. hydrogen peroxide breaks down into water and oxygen when subjected to heat or light.
And no, i have no idea if any of those would create overwhelming foam.
