Bring open-ended STEAM play to life with this 106-piece Pastel Ball Run Pack — a hands-on set that invites children to design, build, and experiment while exploring gravity, momentum, balance, and problem-solving. The kit pairs pastel connector tiles with eight wooden balls and a variety of clear, fluted and specialty run pieces — including split/Y tubes, stair/soundscape pieces, S-bends, U-shaped bends, slides, right-angle and straight tubes — so kids can create sensory runs, mazes, racing tracks and large-scale engineering builds that encourage creativity and cooperative play. Construct sturdy, safe builds thanks to non-toxic ABS tiles (BPA- and phthalate-free, ultrasonically sealed and riveted). Recommended for ages 3+.
