| Insert description of demonstration, how is the demonstration preformed. | This demonstration show the thermal expansion of the material. Once you put the lead brick on the one end of the rod that means it can hardly expand on the side. While you heat the rod by the burner, the rod is starting to extend to the other side. You will see the straw spinning while you heat the rod because the extension of the rod makes the pin spin forward. Due to this, it makes the straw spinning. |
