Sitting on nails
Why not try our fakir’s bed of nails? Why can we sit on many nails without hurting ourselves, while sitting on one nail is very painful?
Sit down on our seats of nails. Sitting on a nail is usually very painful, but if there are sufficiently many nails, the body’s weight is distributed over many nails and the pressure exerted by any one nail is not large enough to cause any risk of puncturing the skin. The same phenomenon makes it possible for you to stand on a sheet of raw eggs. Try this experiment at home.
