Dissolving Substances Experiment Insights

The video tutorial from Lighthouse Lab demonstrates how substances like sugar and Skittles dissolve in water. It begins with an explanation of the dissolving process, where water molecules break apart substances into tiny pieces, forming a solution. A demonstration with sugar cubes and food dye illustrates this concept. The main experiment involves Skittles arranged on a plate, with water poured over them to show how the colors dissolve and spread. The video concludes by encouraging viewers to try similar experiments at home.
