Description
These cast iron bar breaker rods are replacement break rods supplied in a pack of 10 for bar breaker thermal expansion demonstrations. Each rod fits through the hole in the bar breaker apparatus and acts as the sacrificial element. When the bar is heated and expands, force builds until the cast iron rod fractures, producing a loud report as a clear audible indicator of expansion.
Use under appropriate supervision. Keep hands and faces clear during heating and the break event, as fracture and noise are sudden.
