Abstract. The design and use of a molecular model set that can be easily pulled apart are described. Each atomic piece is constructed from spherical magnets and metal tubes installed in colored ping-pong balls. The magnets can roll inside the ping-pong ball and be drawn to other magnets outside the ball, allowing assembly and disassembly of the molecular models. The molecular model set can be used to illustrate simple chemical reactions and constitutional isomers.
