Whoa. Just tried it out. Today's question is:
If you were to have a certain type of boiled breakfast, an odd gray-green layer may form around its core. What chemical compound causes this discoloration? -

How to find the answer: Searching [boiled breakfast] will get you hard-boiled egg. Searching [hard-boiled egg green] shows the green layer on hard-boiled eggs is a reaction of iron and sulfur. Search [chemical reaction iron and sulfur]. This yields results for Iron (II) Sulfide, the name of the compound.
