Egg cartons and beverage holders can be used as models of atoms, with their dimples representing orbitals. Each dimple can hold up to two objects such as milk jug caps, plastic eggs, and cup pieces to represent electrons in the orbitals. Partially overlapping the trays by stacking the dimples represents chemical bonding and produces molecular models resembling Lewis structures. The models can be easily made from materials that can be readily found grocery stores and fast-food restaurants.
This article describes a game aimed at helping students become comfortable using dimensional analysis. Designed to mimic the popular card game UNO, MOLE-O encourages students to think about how to set up a stoichiometry problem utilizing a deck of UNO-like playing cards.

Nothing is more iconographic to Chemistry as the Periodic Table, and Signal Flags are colorful and dandy design that are iconographic to the seafaring community. While teaching chemistry at the U.S. Naval Academy, the author used Signal Flags to make the Element Symbols giving a structure that is immediately recognizable, yet somewhat mysterious.
