Bed of Nails
★Exhibit Content: Pressure, Force ★Interaction: Electromechanical Interaction ★Operation: Lie on the nail bed, press the start button, the nails of the nail bed slowly rise, experience the nail bed. ★Exhibit Description: The exhibit mainly consists of a platform, stainless steel nails, operation buttons, motors, etc. The size of the nail bed platform is similar to a single bed, and it is composed of many steel nails forming a nail board. Two buttons are set, one for rising and one for lowering. With simple experimental setup, the exhibit demonstrates in a highly interesting and visually enjoyable way the magical phenomenon that visitors lying on the nail bed will remain unharmed. ★Scientific Principle: The nail bed is made of densely and evenly arranged nails. The weight of the human body is distributed among many nail tips, so the pressure on each nail is extremely small, far from enough to pierce the skin. According to the principle pressure = force / area, the larger the force-bearing area, the smaller the pressure, so lying on it is safe and painless. The density of the nails increases the force-bearing area of the person and reduces the pressure (and the effect of force), so that visitors will not be pierced by the nails and thus remain safe.
