Petri dish
Pattern formation is when a solution containing NaOH, glucose, and dye is poured into a Petri dish that is open to the atmosphere. This will result in solution changing its structure over a period of time. Structures arise from molecular transport through diffusion and chemical kinetics. Patterns formed in the Petri dish can be described as a mosaic pattern; web-like, dynamic spiral, branching, and lines connecting to each others.
