In science one year, we did a test of dropping a water bottle from different heights over a Pringle, and we had to protect the Pringle with a paper. But how would increasing the height increase the force is the mass and acceleration is the same?

If something gets crushed or break, in general suffers plastic deformation, it requires energy. Thats pretty much the starting point of inelastic collisions. In such collisions the kinetic energy isn’t conserved but goes into the plastic deformation of the object.
Kinetic energy is a function of velocity. If you drop something from a greater height it will reach a higher velocity before it hits the ground. (assuming no air resistance) More velocity means more kinetic energy and unless the object bounces back significantly most of that kinetic energy goes into deforming the object.
So force here is not that relevant or rather useful when we talk about the impact of some thing like a projectile (a bullet) we care about its kinetic energy because the destructive power (how much it can deform materials) is directly linked to its kinetic energy. Thats why you often hear people referring to these as kinetic energy weapons.
