Terrifying instruments of religion and war, Aztec Death Whistles were used to summon spirits and create horror and fear wherever they went. These whistles emit a piercing scream that sounds like someone being tortured in horrible agony. The Screaming Death Whistle is produced by Aztec artist Rafael Itzcoehua and team. Capable of producing 125+ decibels of bone-chilling realistic screams, it is the perfect whistle to terrify and delight your friends. Or use it as a camping whistle, hiking whistle, outdoor survival whistle, or even a safety whistle. The Aztec Death Whistle skull is a link to historic and Ancient Aztec culture. And it’s a collectible piece of art you can display in your home. It's perfect for Halloween and Dia de los Muertos (Day of the Dead) as well! Disclaimers - This is a Musical Instrument! To use, blow gently into the top with a long breath, not short bursts. To vary the whistle's sound, experiment with modulating your breath & moving your cupped hand below the whistle as in the video found with this listing.
