How Can You Tell if a Silicon Wafer's Orientation is (111)?

The easiest way is to take a hammer and nail to the wafer! Put the nail on the wafer's center. Hit the nail with the hammer. If the wafer breaks into four pieces, the the crystal orienation is (100). If the wafer shatters, then it's (111).
