How to make crop circles ?
Anybody can make a crop circle with simple tools. The only tools you need are rope, boards or metal pipes and a willing crew. Here is a common way of making crop circles. 1 A stake is hammered into the field at the center of the area where the circle will be created. 2 A rope is tied to the stake and stretched to the edge of the circle. 3 A crew member at the end of the rope makes a perimeter by walking in a circle around the stake. 4 Boards or heavy pipes are then dragged over the crop to flatten plants within the space. 5 Outside the new circle, rings can be made by leaving sections of the crop undamaged.
