I've often wondered if after the reaction takes place, and after the temperature drops, would it be safe to play with? The foam itself is basically dish soap, coloring, and the oxygen released in the reaction, but I'd be hesitant to dive in, just in case.

That's a good question. The H2O2 you get from the store in the brown containers is a 3% solution. 35% is probably rather caustic, but people have been (mis)using it for awhile now for all sorts of cure alls. Probably not super harmful after the reaction because it strips and oxygen ion off the peroxide and you're left with water.
On the Potassium Iodide side I really don't know. Before the reaction it's a salt generally used to block radioactive iodide. It's not particularly harmful.
After the heat of the reaction though, you're pretty much left with soap water though. It might dye your skin though!

I'm not sure if there would be any KI in the foam itself, or if it would all be at the bottom of the container.
The KI is used as a catalyst, which is a chemical that helps a reaction along without getting used up. The reaction itself is the decomposition of H2O2 into H2O and O2.
But smoking is definitely a bad idea around this, FWIW
Love you, too
