(1) With the increase of pressure, the deformation of the balloon becomes larger, which shows that the greater the pressure, the more obvious the effect of pressure.

(2) It was observed that the balloon in contact with the palm was slightly deformed, while the balloon in the fingertip was obviously deformed. The conclusion is that when the pressure is the same, the smaller the stress area is, the more obvious the pressure effect is.

So, the answer is: big; When the pressure is the same, the smaller the stress area, the more obvious the effect of pressure.
