Heating the bar and then comparing it to the gauge provides an excellent visual demonstration of thermal expansion.
For illustrating expansion by heating and contraction by cooling.
Comprising a bar of iron mounted on a support rod with wooden handle,
and a brass gauge with a cut-out which barely admits the bar lengthways
while cold, and a hole which passes the bar endways only while cold.
