Yes, I certainly agree with Kate.

During an Astronomical Observatory session at
Pittsburgh's original Buhl Planetarium and Institute
of Popular Science, one of our Observatory volunteers,
John D. Weinhold, would always challenge children to
go home and use a magnet to find magnetic dust around
the house that could have come from a long-ago
burned-up meteorite.

Have you thought to find a source of sand with a high
magnetite
content?
It's great fun to play with and an "aha"  to visitors
that some of the
black grains in sand is actually magnetite.
