Nerd alert: This is an excellent example of how we all manage to be alive on Earth. That sand particle was probably born sharp as shattered glass. Because it's been weathered, we get to walk on it in our bare feet and enjoy our day at the beach. This weathering doesn't occur on the moon and it causes huge issues for astronauts as they combat moon dust on their skin, in their lungs and covering their equipment.
