Bar & Gauge, Brass with insulating handle
The classic brass Bar & Gauge apparatus to prove and demonstrate the effects of heating a metal. If the bar is heated or if the gauge is chilled in ice, the bar cannot fit the gauge both in length and in diameter. Unlike the Ball & Ring, the two are not chained together.
The IEC item is carefully machined and matched for size so that the experiment works.
