Understand Uncompacted Gravel and Void Space

What happens here

The video transitions to a large pile of 3/4 inch limestone, also identified as CA6. The narrator picks up a handful of this uncompacted gravel, demonstrating that while individual stones are already inherently compact, when a large quantity is simply piled or dumped, there is a significant amount of "air space trapped in between each individual stone." This is referred to as "void space." Examine the loose gravel and conceptualize these empty spaces.

Goal: Identify the characteristics of uncompacted gravel, specifically the presence of void space.
