For this trick, take a piece, two or three inches long, of a stem of
a clay tobacco pipe, taking care that one end is quite even; with a
knife or file, work the hole at the even end larger, so as to form a
little cup. Choose the roundest pea you can find, place it in the cup,
and blow softly through the other end of the pipe, throwing back
your head while you blow, so that you can hold the pipe in an upright
position over your mouth.
The pea will rise, fall and dance in its cup, according to the degree
of force you use in blowing, but you must take care not to blow too
hard, or you may blow it away altogether.
