Happy Atoms 2D: Interactive Chemistry Puzzles by Thames & Kosmos

Making sense of the world of atoms and molecules is now as easy as piecing together a jigsaw puzzle! Now you can use Happy Atoms, the revolutionary chemistry teaching tool, in a low-cost, two-dimensional jigsaw-puzzle-style edition. In this version, the three-dimensional plastic atoms have been replaced with flat, cardboard puzzle pieces. Just like in the original versions, you can build more than 17,000 molecules by combining the atoms of 16 elements and scanning them with the app to identify the molecules and learn about them. This kit comes with the same full-featured version of the Happy Atoms app that comes with the original versions of Happy Atoms. Bonus: Includes a sample 3D Happy Atoms water molecule — H2O!
