These things are just way too cool. They were literally modern warfare for the Aztecs. They have been described as the sound of ‘a 1000 screaming corpses”. I’ll post a video but really, unless you got amazing headphones or speakers, it won’t do it justice.
My cat absolutely hates this sound. To be fair, she doens’t like any loud/sudden sounds But if you want to annoy your neighbours in the middle of the night and/or freak them out…..one of these will do the trick!
