Ellingson - Here is a quick demo of a small #peppersghost...

Repost (@emilia.science) This beautiful demo shows the displacement of copper from copper chloride by aluminium.In a flask, water is mixed with conc hydrochloric acid and copper chloride. Then some aluminium foil balls are added in. Hydrochloric acid conc is used to remove the aluminium oxide layer so the reaction can take place. The reaction will produce hydrogen gas that can be ignited to produce a beautiful green/blue light, due to the copper. #STEMulateYoungMinds #Chemistry #scientist #scien
