WOOD is flammable and spontaneously combusts at exactly 600C. At high temperatures, the wood turns darker until it is coal black, then it explodes. On the other hand, if below freezing, the wood will turn ice blue. NEUT can pass through WOOD, whilst deforming the WOOD. VINE will grow on WOOD when you place VINE next to WOOD. This will not stop until all the wood that can be reached is covered with PLNT/VINE. PLNT turns into WOOD at NEUT's contact. Can not be pressurized into coal. When a high-velocity particle hits WOOD, it will turn into SAWD.
