Rooftop Fun Factory May 4, 2010

Learning is simple with simple machines. Come outside and play in the hands-on 'Rooftop Fun Factory.' Use a pulley to lift yourself off the rooftop, get dizzy spinning the Archimedes's screw or turn the windmill using a giant ball that falls to the roof. Enjoy blowing bubbles and watching them float away, and check out the views of downtown Chattanooga with the telescope, or relax under a giant tent and play a game with an oversized chess board. The sky's the limit at the Rooftop Fun Factory.
