Build, test, and launch thrilling marble runs with this stunt-filled construction kit. Sixty colorful, durable track pieces snap securely together so young engineers can invent wild custom courses packed with action.

Send ten glass marbles zooming through gravity-defying tricks like the 360-degree flip, air jump slide, bumper steps, and swirling spinners. Every roll turns fundamental physics concepts like momentum, friction, and kinetic energy into interactive, hands-on fun.

Follow the illustrated eight-page experiment guide to test new layouts or race your marbles against the clock. When the physics fun wraps up, neatly pack all the components into the included storage bag.
