RiverWorks is part of the latest renovations make to the National Mississippi River & Aquarium Museum. The exhibit includes three mini-exhibits that encourage visitors to take a hands-on approach to learning about the role of water power in the motion of a river. The large water wheel at the entrance of the exhibit is powered itself by water that pours onto the main wheel. The water table represents a river which can be interacted with using an archimedes screw, water wheel, and water locks. The water table even has an indoor thunderstorm, where water showers down from rain clouds that give off the sound and lighting effects of a real thunderstorm. Last but not least, the water cycle area is interacted with by cycling on exercise bikes to convert energy into rain power. A bucket fills up with water as a visitor cycles, and finally tips onto a rain cloud in order to cause a rain shower.
