Weekly science videos like Which came first, the chicken or the egg? and What if you stopped sleeping? get millions of views a pop. In this video, Toronto creators Mitchell Moffit and Gregory Brown challenge you to test your hearing. Try it out. How much can you hear?

Living Piano
Twelve notes. Twelve opera singers. One instrument … and hundreds of thousands of YouTube views. Canadian educational broadcaster TFO brings opera to the people in this musical video from the Québec City Opera Festival, featuring a “Living Piano” of singers who elegantly belt out notes as the giant keyboard is operated by passersby (and the occasional dog).
