Description:
Bell Thermal Expansion
Specification:
Bell Thermal Expansion - Because this demonstrates both linear and spherical expansion, it's an
improvement upon the traditional version. Both the rod and gauge have
wood handles for safety. At room temperature, the rod fits snugly inside
the gauge's slot; both ends fit into either hole. When heated, the rod
no longer fits in the slot and fits one - but not both - of the holes.
With instructions.
