Why is the bed of nails trick safe?

The bed of nails trick is a stunt in which a person lies down on a bed of nails without being impaled. The trick works because the nails are not driven all the way through the board, so they cannot penetrate the person's skin. The person's weight is distributed evenly over the nails, so the pressure is not enough to push them through the skin.

In order to perform the trick safely, the person must lie down on the nails very slowly and carefully. If they move too quickly, they could slip and impale themselves on the nails. They must also keep their body as still as possible, so that the nails do not move around and cut their skin.

The bed of nails trick is a dangerous stunt that should only be performed by experienced professionals. Even experienced performers can be injured if they make a mistake.
