I dated a soprano who could rattle the rafters with her voice. She could probably do the Ella Fitzgerald/Memorex ‘ breaking glass’ commercial.
That “Breaking glass” thing is for real, but it’s very very thin glass.
I once sang to some spinner dolphins and lured them to our boat. The dolphins could hear me, but the people on the boat couldn’t! hahahaha.
When the dolphins realized there wasn’t anything in it for them, they left! LOL!
