You can blow bubbles through a chunk of porous oak, provided it is cut
the right way.  It has to be a bit with the xylem running vertically,
preferably summer wood.  We do this demo in our Plants and People
course.  You don't get free-floating bubbles, but you sure do get foam
on the soapy-water end.
