Question: What happens when you mix sodium sulfite, citric acid, and sodium iodate? Close, but the right answer isn't "Who gives a shit?" Also, you should really check your attitude at the door to the lab. There is very little room in science for that kind of wanton brusqueness. The correct answer is this:
The chem version of your toilet after Jager night.
When you mix the aforementioned ingredients in certain proportions, you end up with a finicky liquid that starts out transparent, but then turns deep black in an instant. This is handy if you want to observe something called an "iodine clock" reaction, or convince your cousin that he truly is haunted by a Japanese well ghost after watching that YouTube clip you sent him. Put simply, a chemical clock reaction happens when specific compounds are mixed in such a way that their concentration slowly changes. When it passes a certain threshold -- BOOM, you've got Shenanigoats climbing everywhere!
But wait, there's more. By changing the proportion of the ingredients, you can even reverse the reaction:
