This vial holds billions if not trillions of  nanoparticles. Amazing that so many tiny particles can be added to water and the solution remains pretty clear.

This property is one reason the food industry is so interested in using nanoparticles in food products  — they can add nutrients without changing the clarity of a beverage, for example.

Just to get an idea of how small these particles are:  these spheres measure a mere 100 nanometers. This means it would take over 1600 trillion of the 100nm particles to fill one square inch cube (a solid cube). That’s a lot of particles.
