This is only on topic because many of us drink coffee and it does involve wood. I went to my administrators office a few minutes ago and got a cup of coffee from one of those instant dispenser brewers that use the individual cup cartridges. I added sugar and grabbed a wooden stir stick which became limp shortly after I started stirring and within a minute, the wooden stirrer broke apart. No noticeable knots in the wood. I'll still drink the coffee- it's part of my circulatory system - but I wonder what it would have done to a plastic stirrer.
