Sand particles are relatively large (by definition from 2- to 5-hundredths of a millimeter across). At the larger end of this range, you can easily see them with your naked eye and feel them ...

Watch sand defy gravity and flow uphill thanks to “negative friction” Applying magnetic forces to single iron oxide-coated particles spurs strange collective motion.

The pure sand-derived synthetic silica particles have a high surface area that allows them to absorb a lot of sugars, fats, and digestive enzymes from the gastrointestinal tract.
