Geeky Emergency Whistles

These geeky whistles are tools for alerting your community to potential danger. They are super loud at over 100db and are not toys, they are emergency tools and ideally should only be used when you are using hearing protection. I used Jonas Daehnert’s 4mm emergency whistle to create these geeky versions. There are plain versions and also new versions that have the info for Minnesota's Immigrant Defense Network on the back.
