What is Qvolution? The evolution of the cube (to include curves)—and of imaginative learning. Kids have a blast designing ever-more-incredible ways for marbles to roll over, down, and along courses they create by fitting together beautifully constructed, magnetized cubes (with either curved or straight rails inside) and a slew of separate 7"-long straight rails. Let the experiments in engineering—and fun—roll. The Standard Set (38 pieces, 4 marbles) is a great way to create fun marble runs from cubic 3-dimensional constructions that can bend. Cubes are 2½"sq.; straight and incline rails are 7"L.
For ages 3 and up. 38 pieces, 4 marbles.
