LEGO's are huge now-a-days. With video games, toys, movies, TV shows, etc. But no matter how much we love them, the one thing painful about LEGO is how much it hurts when we step on one.

How can such a small piece of plastic cause to much pain to an adult? Well here comes the science behind it! My heart goes out to you if you step on a Lego brick that is on a tiled, rather than carpeted, floor.
