For imaginative kids with a passion to build, Chaos Tower has infinite construction possibilities. Over 600 pieces allow inventors to configure structures up to 6 feet tall or 5 feet wide. Including an AC-powered motor with adapter and tons of stunt pieces, kids can create perpetual motion models by designing loop-d-loops and sharp turns. A long chain-drive lift, chimes, trampolines, basket elevators and swirling vortexes propel balls while kids experience a hands-on lesson in physics and kinetics. Chaos Tower is lightweight, fully portable, and easily assembled without any tools. Item requires an additional oversized shipping charge of $10.00. Sorry, rush shipping is not available.
