Other than the presence of Laurel&Hardy in it, The Tree In A Test Tube would pass into oblivion that most educational films do. The film is one of the Pete Smith specialties that MGM used to turn out by the dozen, some with humor others that attempted it, but didn't succeed.

This is one of them as MGM and Pete Smith thought that the mere presence of Laurel&Hardy would hold the audiences attention as the audience listened to a litany of the many uses that wood has in our daily lives.

Maybe if Stan&Ollie did some of their shtick during the short it might be better remembered. As it is it's for Stan&Ollie completists only.
