No, you won’t die if you hear the sound of an Aztec death whistle, but you’ll hear it a lot in this video, and you might want to be ready with the volume control. It can cause a jump scare in the people in the next room, or make children cry. It’s a small instrument that looks like no more than a duck call, but the sound it produces is like a terrified person screaming beyond control. If you were in enemy territory, or had the possibility of an invading army, hearing this in the night would make the hairs on your back rise up. Not knowing what’s going on and hearing what sounds like someone dying would ruin your evening considerably. James Orgill of The Action Lab (previously at Neatorama) actually made some Aztec death whistles with a 3D printer. He tells us both the history and science of these whistles, and blows those darn whistles quite a few times. That’s an interesting and sneaky way to lead up to an ad for the 3D printer. -via Digg
