Blasters have been tested with batteries and they make a "spark" sounds when triggered. But they don't work as intended and considered broken. I don't know if they are a easy fix or not.
Green rangers flute might need new batteries but middle circular trigger/button doesn't work. Both circular triggers on sides work fine along with square trigger and they make continuous sounds when pressed.
