Swing Wing

What Is It?

It's a gizmo from the '60s.  Kids wore a beanie cap with a swinging bunch of streamers attached.

What Happened?

Kids would wack themselves in the head with the streamers...but the bigger issue is the neck and back injuries whipping your head around would cause.

Aftermath?

I'm not sure, they were made in the '60s and don't seem to be made currently.
