It was from my son and daughter-in-law who live in
Houston. I'll ask her where she bought it and let
you know.
If a person had a source for buying test tubes, they
could use a drill with a large drill-bit of the tube size to
make holes in a 2"x4" (or similar) piece of wood. Then,
just stand the tubes up in the base which could be any
shape desired.
