Now you must be wondering, what evil can be conducted with some dirt, concrete and a plank of wood? Well, I’ll tell you! You see, the missing part of this equation is bamboo, of course! While reading up on the curious little plant for a herbology project, I came across the fascinating little tidbit of information that young shoots of bamboo have been known to grow so quickly and persistently that they can damage the foundations of houses. There were also unproven historical accounts of people being tied down over young shoots and over the course of a few days the shoot grows straight through the person. These accounts were never proved but I was in luck. Magical varieties of bamboo have been known to be so durable and persistent in growing that they can penetrate up to 3 feet of steel over the course of a week. This was perfect for what I had in mind.
