When Hydrogen gas is passed over Copper Oxide, Copper and steam are formed.
Equation:
                         CuO + H₂ ------------> Cu + H₂O
                                                              (Steam) 

Setup:
We take a test tube and keep it in semi-inverted position. Then we pass hydrogen through a small pipe to the copper oxide. The copper being heavier will stay in the test tube and the steam will flow out through the open face of the test tube.
