When I was a kid with a Nintendo Entertainment System (NES), sometimes my games wouldn’t load. But I, like all kids, knew the secret: take out the game cartridge, blow on the contacts, and put it back in. And it seemed to work. (When it failed, I’d just keep trying.)

But looking back, did blowing into the cartridge really help? I’ve talked to the experts, reviewed a study on this very topic, and have the answer.
