speaking of peroxides and superoxides, i was doing a chem competition yesterday (i went in alone without a partner and won the event with a perfect score:)))) that involved using calcium metal. i reacted the calcium with water and it bubbled, but not too vigorously, then it stopped. half an hour later i was done with the lab practical and the questions and talking to the chem teacher supervising the event when i snapped my fingers once and noticed that at that very instant the calcium started reacting again, much more vigorously than before. i figured that it was an oxide/peroxide/superoxide layer that was broken through at the very moment i snapped my fingers. cool occurrence
