Using a set of 50 atom models representing 16 different elements, you can assemble your own molecular models. The atoms stick together easily with magnets: metal tips on the ends of rubbery arms, which represent free electrons, snap onto magnetic bonding sites on the atom spheres, which represent empty spots for electrons in the atom's outermost electron shell. But how will you know what the molecule you've created is? Using the included app to snap its picture, the app uses a state-of-the-art image recognition technology to identify the molecule. The app recognizes tens of thousands of molecules. With the app you'll also get detailed information for about 120 of the most important molecules. This information can include the molecule's usage, properties, hazards and more! This set includes 52 pieces, and is recommended for ages 10 and up.
