Particles in Blender

Adding a particle system to an object is really awesome if you want to animate hundreds or even thousands of smaller objects or particles. This could be smoke, fire, water, mud, snow, sparks, bees, rocks, trees, ANYTHING! You could use particles in the scene of your animation or even as part of the characters.
