Because without tyloses the whiskey would move vessel to vessel and,
under the force of gravity, drip out the ends of each stave.
I just presented this in class this morning and in lab will demonstrate
it. Take a white oak and red oak twig 1/4 to 1/2 " in diameter [2 - 3"
long] and insert each [snugly] in their own piece of plastic tubing.
Attach the other end to a water outlet and slowly turn on the water just
a little. Drops of water will appear at the end ot the red oak, but not
the white. You can also hook the tubing to a gas jet and light the gas
coming out of the red oak. Just be really careful -- I've seen flames
shoot out 10" from the end of the twig.
I normally practice this first to make sure the twig specimen will
"cooperate" and behave as it should. You don't want to get a white oak
twig whose vessels are not yet completely blocked.
If someone has a more sure-fire demo for this I'd like to use it.
I also ask them why the whiskey barrel halves sold as planters at garden
centers are charred on the inside. [They often assume they are
fire-damaged salvage.] This is a good place to apply one of their
organic chemistry lab protocols [much to their surprise].
