Model 1 The red puck represents smoke particles. The metal balls represent air particles. Model 2
The red particles represent air particles.
The large blue particle represents smoke particles.
The view on the left shows what we see under the microscope.
The red particles are too small to see even under a microscope! Model 3
The smoke particles look like they are moving by themselves.
They are moving because the air particles surrounding them are moving in random motion. The air particles will look like the smoke particles, but much smaller.
