What If Everyone Jumped at Once? What Color is a Mirror? Big Questions Answered in Viral Videos

Michael Stevens knows some­thing about viral videos. Yes, he’s a Googler who works on Pro­gram­ming Strat­e­gy at YouTube. That gives him some pro­fes­sion­al bona fides. But he also rolls up his sleeves and pro­duces his own wild­ly pop­u­lar videos under the Vsauce ban­ner. Per­haps you’ll remem­ber when Stevens asked the ques­tion late last year: Just how much does the entire inter­net — all 5 mil­lion ter­abytes of infor­ma­tion — actu­al­ly weigh?  (That got 1.3 mil­lion views, putting it cer­tain­ly into viral ter­ri­to­ry.) Two weeks ago, Stevens returned with anoth­er tan­ta­liz­ing ques­tion: What col­or is a mir­ror? Hint: It’s not what you think. And now, just two days ago, he dropped this ques­tion on us: What would hap­pen if every­one on the plan­et jumped at once? Catch it below.
