Introduction
The bed of nails has always been the project that excites people the most in science related demonstrations. However, it's crucial to understand the physics concepts that allow the demonstration to be carried out without injury. The main concept behind the Bed of Nails is the pressure formula (P=F/A). According to the formula, the force applied to a surface is equally distributed among the area of the pressure points of the surface. In this case, the surface areas of numerous nails add up to reduce the force applied on the person who rests on the Bed of Nails.
