#1: Does Wood Sink ?

Yes, it does ! Live wood sinks....try to break a twig from your garden and drop it in a cup of water!  Live wood is heavier than water because it is  water-logged . Dry, dead wood does not sink...but it can be  water-logged  to sink again.  We can  water-log  wood by submerging wood for  many weeks . Or  in a few minutes  by putting wood under high pressure in water. See Pine wood samples in the picture above, all kept for 10 minutes under pressurized water.  The sample "AT" to the right  was in water under the highest pressure (1000 PSI) and  now it sinks.....!
