Crush a Plastic Bottle Science Experiment

This bottle crushing experiment never gets old. I loved it as a kid and I still love it now. However, I have yet to try it with a regular plastic water bottle. They are designed to use less plastic than larger soda bottles. It is the reason they have ribbing. However, I have a feeling that the compression of these bottles will be more pronounced.

How does SURFACE AREA affect reaction rate? Increasing the surface area of the Alka seltzer tablet by crushing it exposes more H+ and bicarbonate ions in the water, which increases the number of effective collisions that can occur between particles in a shorter amount of time.This allows the reaction to occur at a faster rate.
