The Double Row Pebble Bridge is an unusual and exciting playground obstacle with moving pebble platforms that kids can step across to get from one side to the other. The platforms are hanging from pendulum-like beams which allow them to sway back and forth. This makes them deceptively tricky and fun to balance on. Fortunately, beams offer a secure and stable place for children to old onto before they take the next step, and each step is chained to the ground to prevent it from swinging too far. This model includes two parallel rows of steps with five platforms each. This makes the crossing easier, since kids can move from one side to the other, or place one foot on each side. As well as making the activity easier and more interesting, this allows multiple children to use it at once, and even pass each other.
