Another failed toy deemed dangerous.
Clackers, popular in the 1970s and revived later, are a dangerous toy consisting of two hard plastic or acrylic balls connected by a string, which are swung to clash together and create a loud noise.
They are infamous for shattering, exploding, or breaking off, causing injury, which led to a 1971 FDA warning.
They were banned or had warnings issued in many areas during the 1970s due to being recognized as a "mechanical hazard.
