Nowadays, the amusement facilities are altitudes ranging from 1.2m to 8m in height. Falling accidents due to carelessness create great risks. If you fall to the ground due to carelessness, you won't be seriously injured if you absorb the shock from the ground.

Even now, such a shock-absorbing floor pavement has been laid so as not to suffer great damage from the fall. However, despite these attempts, the damages caused by accidents are not much improved. The reason for the lack of improvement is that the shock absorbing floor pavement does not absorb shock.

In other words, the shock-absorbing bottom pavement absorbs the impact by reaction rather than by bending deformation. When a shock is absorbed by the reaction, it is almost the same effect as being bounced up again by the repulsive force. Therefore, a child falling down receives the shock in the form of a repulsive force and causes a second accident depending on the direction of the bounce. Sometimes.
