Tony - you are place on a board on your back. A your mouth is covered so you can only breath through your nose. A towel is placed over your face and to your nose, and water is slowly poured or dripped onto it so you feel like you are drowning. It causes no permanent damage, but is very psychologically stressful. We have put our own pilots, special forces types, etc through it in training them to resist interrogation. Supposedly no one makes it through the water boarding without breaking. However, again it leaves no permanent damage.
