When a ball or ring on a handle is heated, the ball will not pass through the ring, but when cooled the ball passes through the ring freely. Comes with support stand. See Enlarge Click to Enlarge Temperature Generator Demo (MS307.6) This generator is driven by the widely water temperature difference. Immerse one metal bar in cooled water and other metal bar in hot water, a few seconds, at the top of small motor will be running fast due to the big water temperature difference. It is good for science education. See Enlarge 1 2 3 4 [5] [«Back ] Go to Top
