The LV aprils fools thing this year was pretty funny but I started paying attention to when I hand plane red oak and noticed that often I don't get solid shavings, rather alot of stringy fibers that can leave alot of real small pieces and dust in the well of my plane. Red oak is so pourous compared to poplar/maple so the same settings will get nice wispy shavings in one and the stringy broken up shavings in the other. When I blow it out they go everywhere and stay suspended for quite some time. In fact, if I am too close when I inhale to blow, it's possible to accidentally suck up some of the stuff.
