Experiment instructions+

E114_S001 The glue stick melted wax at equal distances from each other wooden sticks.
E114_S002 The spot weld rods heated burner.
E114_S003 First, chunks fall off the copper rod, then to the steel.
E114_S004 Finally, all the blocks fall.

Physical interpretation+

The experiment points to the different thermal conductivity of two different metals. In an attempt to design implies that copper is a better thermal conductor than steel.
 

Application in practice+

radiators, coolers, ...
 

Note+

Ensure safety with open fire!
