Beautiful Chemical Reactions - вытеснение металлов

We dropped zinc metal in silver nitrate (AgNO3), copper sulfate (CuSO4), and lead nitrate (Pb(NO3)2) solutions, and recorded the emergence of silver, copper, and lead metals with beautiful structure. To preserve the fragile structure of lead metal, we also added sodium silicate (Na2SiO3) and acetic acid (CH3COOH) to the solution to make it gelatinize.
