Product Description

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. Heating the bar and then comparing it to the gauge provides an excellent visual demonstration of thermal expansion.
