What does he add Potassium Iodide to in this?
In this video, what does he add KI to? ( its at 00.11) Blue suggests a number of things but I presume he is using quite concentrated solutions as
well?

Catalyst to decompose the cc. H2O2.

That's an elephant toothpaste demonstration. The blue solution contained concentrated H2O2, detergent, and possibly a dye, but I'm guessing that the
blue color was just from the detergent. The KI forms I3- ions which catalytically decompose the H2O2 by the following equation
: 2H2O2 --> 2H2O + O2. The oxygen is produced extraordinarily quickly and is captured by the detergent forming lots of tiny bubbles, creating a
large amount of foam.

Alright then, guess that demonstration goes out the window, 6% peroxide is the highest I can get, 30% I could make but only a few mLs at a time.

Yeah,with 35% H2O2 its great fun.I want to see with H2O5(O3 bubbled into peroxide).
