I printed 100 Aztec Death Whistles to pass out instead of candy on Halloween night! They sound like a person screaming at the top of their lungs. People get startled even when you explain to them what it is and then they hear it for the 1st time.

Rules for the kids: 1. Don't scare people passing out candy, they will stop giving out candy…

1. Don't take it to school, they will just take it away from you and your fun will be over…

2. If you hear someone blowing one, you must reply with your own whistle!
