1. *Discrete Shadows*: When light passes through a pinhole, it creates a discrete shadow on a screen, indicating that light is composed of tiny particles (photons) rather than being a continuous wave.

2. *Brownian Motion*: The random movement of particles suspended in a fluid (like pollen in water) demonstrates the collisions between visible particles and invisible molecules, supporting the idea that matter is composed of tiny particles.

3. *Crystal Formation*: The formation of crystals, with their repeating patterns and shapes, suggests that matter is built from tiny, indivisible particles (atoms or molecules) that arrange themselves in a regular structure.
