Molecular model kits are commonly used in chemistry classrooms to help students visualize different molecules and chemical structures. Being able to physically manipulate atoms helps clarify bonding, shape, and compound formation in a way that 2D diagrams often cannot. However, commercial kits typically cost around $25, with some larger sets even costing as much as $62, and it is easy to run out of key components when multiple students are working at once. With these models, teachers can produce as many molecules or atoms as needed, allowing for more students to experience this fundamental concept in its true 3D form.
