Granular Material Task

Topic for discussion.

What is considered "granular material"? My Science Olympiad group was planning on using BB pellets for this task and the final task. Do BB pellets qualify as "granular material" or do we have to use sand or gravel?

Here is the official clarification from soinc.org, regarding the definition of an "organic granular material":

Granular material is a conglomeration of discrete solid, macroscopic particles characterized by a loss of energy whenever the particles interact (the most common example would be friction when grains collide). Thus, organic granular material could be described as a collection of pieces of organic material. Some examples of organic granular materials are rice, coffee, corn flakes, sugar, nuts, popcorn, coal, pieces of cork, leaves, etc.

Ignore the part about organic, as that only applies to Keep The Heat/Thermodynamics.

Just to be sure, I submitted an official clarification. Not sure if someone else already has done so.

I submitted one on if a funnel is a container.

Sorry, I missed that post because I scrolled down to the bottom to look for new posts, but good question.
