What is Brownian Motion?
All matter is made of tiny
The particles are atoms, ions or molecules.
In a liquid or gas, the particles move at random.

particle (shown as a blue ball)
has a jerky motion.
As (invisible) air molecules collide with the smoke particle,
they push it about in different directions at random.
