I designed and 3D printed a sling whistle. Based on the physics of a normal pea whistle.
Print out both parts, drill a hole onto a center of the bottom of the bigger part, fix into it 1-1.5m wire into the hole. Put in the endcap (maybe some glue required). Use it carefully! (Take care on the windows, domestic animals, etc...)
