The experiences you can read in the following lines can surprise you. Moreover, you will find essays that can succeed in any show. But really, taking advantage of the characteristics of inertia, you can do curious things.

At the ends of a broom we insert a needle that corresponds to the longitudinal axis of the broom. Then a glass is placed on each of the two chairs and the broom is placed on them, but it rests on the needles. In this situation take a strong stick and hit the center of the broom with a strong blow. The broom is broken, but the vessels remain intact. Amazing! However, physically, there has been the phenomenon of dispersion of the molecules that suffer the impact before transmitting the movement to the neighbours, so it does not reach the glass any movement.

This time I will ask you skill. Let's accumulate some checkers over others. Then hit with a fine ruler a tile from the bottom. What happened? That the tab column has not been broken. Why? You have to reason.

Yet it seems that inertia is out of our lives. This is not true, much less. Can we stay in an intense race? Or if we go inside a car and we have to brake sharply?

Examples of this type are thousands. To see if you are of small inertia and you think fast.
