I love snow globes.
Have you ever wondered what makes the glittery stuff inside the globe drift down slowly? It really does look like falling snow?
One factor is the viscosity (thickness) of the liquid, and another factor is the buoyancy of the floating “snow.”
Viscosity is a fancy scientific name for describing the resistance of a fluid (gas or liquid) to flow. It could be described as fluid friction, which is a resistance to motion.
Buoyancy is the upward force of a fluid that keeps things afloat in it.
