Arcobaleno, Rainbow Arches Set

Arcobaleno ("rainbow" in Italian) is a puzzle and a construction set rolled into one. Children nest the asymmetrical arches into the round wooden frame; solve structural problems as they build an inverted cone or a double tunnel; and tap their imaginations to create bridges, domes, towers, spiral houses, and fascinating forms. Includes twelve wooden arches in a 10 x 1.25 inch frame. Recommended for ages 3-8 years.
