Diffusion - Part 1: Skittles Demonstration

The video tutorial demonstrates diffusion using Skittles and water. The instructor explains that diffusion is the mixing of substances by the natural movement of their particles. The experiment involves arranging Skittles in a bowl, adding warm water, and observing the diffusion process as the colors mix. The instructor suggests trying variations of the experiment with different liquids or candies. The video emphasizes the safety of the demonstration and encourages viewers to form hypotheses about the outcomes of different setups.

• In a circle

• Randomly scattered

What causes the colorful sugar water to move towards the center of the bowl?

• Magnetism

• Gravity

• Heat

• Wind

What happens to the colors of the Skittles if the diffusion process is allowed to continue for a long time?
