Product Code : HE0014
Description: 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.
