When I taught physics, it was a requirement that all my students build a
crystal radio ... great fun by all and a couple went on to get a ham ticket!
When I was in 5th grade I built the "Fox hole radio" and never got it to
work. An old time gave me this tiny glass tube with two wires sticking out
of each end and said, "try this." Worked FB and I hid it under the razor
blade ... got a "A" on my science fair project!

Fox Hole radio... I helped a pre med student build the radio for one of
her science projects a few years ago... It worked! And she got an A for
her project. She is now a fine Doc with 3 great kids!
Non judgment day is near.

I had an aunt that lived with my grandma. They slept in the same bedroom
and she wanted a radio to listen to without bothering her mother. We got
a
crystal set from Burstein Applebee and I hooked it up for her -- It
worked.
I think I was in the 6th or7th grade.
I seem to also remember a Gillette Blueblade/pencil lead arrangement -- I
think it was called a "Foxhole radio."
