HAHA you guys are funny, tree power? most wands aren't even wood. No the real use for wands is as a focus point for energy, and yes your finger is also a focus point for energy. A wand essenially can just be alternating layers of orginic and non-organis stuff wraped around a tube with one end sealed off, this will attract and trap energy inside it usually sending it out the open end. Wands are really only usfull for beginners who can't focus energy like me
