Recently, the analytical research by finite element method is actively done for the brain damage clarification when impact loading is received to the head. However, some basic phenomena are left unsolved due to a complex structure of the head including cerebrospinal fluid (CSF). In this research, in order to observe the phenomenon mentioned above and to verify the validity of the numerical analysis, impact experiment with a double acrylic container filled with water so as to be observed in dynamically and visually was done and the following conclusions were obtained. 1) A strong negative pressure has been generated even on the impact side. 2) The outer container doesn't bend by touch with the inner container even if the impact is strong enough for the container to be broken. 3) As for the influence given on the pressure fluctuation in the container, the bend of the container gives larger influence than the acceleration of container.
