this how you make a pecil holder using wood you get a shape of a wood and fix it with wood
Using cupric oxide (CuO, copper(II) oxide), a black powder, it will make hydrated copper sulfate (CuSO4.5H2O -blue crystals) anything left over is simply un-reacted chemical. As the excess water evaporates and if heated it will make anhydrous copper sulfate (CuSO4) a white powder.

the copper reacts with 02 in the air to make copper oxide, which is black 2Cu+O2--> 2Cuo
Copper oxide, which is a compound from the two elements copper and oxygen. When copper is exposed to oxygen for a long period of time, it begins turning green. The green is Copper oxide.Copper oxide can refer toCopper(I) oxide (cuprous oxide, Cu2O), a red powder;Copper(II) oxide (cupric oxide, CuO), a black powder. (Source wikipedia)
