Play set:2 Stars & Crystals

This kit for making polyhedrons out of wooden toothpicks and plastic joints promotes learning about geometry and play. The instructions urge kids to have fun even as they carefully construct their models (in language that might strike some as particularly aimed at hippies from the 1970s experimenting with drugs ): "Go! You can make many forms from your kit. Create your own designs. Take your time. Enjoy your trip."
