Hi, You rub the nails on the each hand against the nails on the other hand back and forth. It makes a funny sound. You should do this for 5-15 minutes at a time whenever you can. My mom does it during TV watching. I have started to do it at every red light or right before bed. You will feel a tingling in your hands after. Fast or slow whatever feels good, I do fast I figure it will stimulate my head! It is ancient accupressure. It also prevents white/gray hairs. Good luck.
