The Strength Of A Single LEGO Brick

The Strength Of A Single LEGO Brick

Why does stepping on a LEGO hurt so badly? First, the bottom of your foot is a sensitive area with many nerve endings to communicate pain. Second, the bricks are designed to be extremely hard, meaning they will withstand the pressure of your weight. And because the bricks are small, they hurt even more—pressure is equal to the amount of force divided by the area to which that force is applied.
