Koontz - The Chaotic Pendulum

A cardboard structure with magnets makes a pendulum swing like mad! Seventeen pieces of recycled cardboard fit together tightly as you follow the detailed building guide to build the pendulum's base. Place three of the included magnets between the two bottom panels. Suspend the fourth one above them by a string. Let it go and then watch as the magnetized pendulum moves, spins, and swings unpredictably and continuously every which way from the power of the magnets. Construct with the recycled cardboard and magnets to make a pendulum toy that's tough, durable, and packed with fun. Scientific learning is easy, safe, and eco-friendly too.
