Product info

Build thousands of molecules from plastic atom models that connect easily using magnets. Experiment on your own by snapping together atoms to form molecules, or follow detailed step-by-step instructions for 150 molecules. Because the physical atom models already have the correct number of free electrons and empty bonding sites, it is difficult to build a molecule that doesn’t actually exist!
