Romp is free standing oscillating magnetic pendulum that is sure to amaze you by how “random” its movements are. Because fields are created by the magnets they act like hills and valleys, the pendulum darts and dodges through the fields during each pass over the playing field. Romp is easy to put together (only requires screwing in 1 screw) and provided hours of enjoyment, it should be on the top of your wish list! Comes with 9 magnets, a powder coated metal base, free swinging pendulum, and instruction book with fun facts and games. Romp demonstrates pendulum motion, magnetism, and chaos. When the pendulum is lifted above its resting position, you give it energy. This energy, called potential energy, is converted into the energy of movement, or kinetic energy, as the pendulum swings down after being released. However, a pendulum is an oscillatory system and the kinetic energy of the pendulum is converted back into potential energy when the pendulum reaches the end of its swing. If there is no air or pivot friction, the principle of Conservation of Energy would continuously transform the initial between potential and kinetic energy and the swinging would continue forever.
