A simple apparatus for demonstrating the expansion of solids when heated.
  • At normal temperature, the bar's length fits into the gauge's jaw and the bar's diameter fits into a hole
  • When the bar is heated, it fits neither jaw nor hole
  • Demonstrates that expansion occurs in both length and diameter
  • Gauge has no handle and can therefore be heated to demonstrate that bar and gauge fit when both are heated
