In this video we make silver powder using electrochemistry. The process is pretty simple. Make a solution of 1g silver nitrate in 50mL water. Submerge an anode made of pure silver (i'm using silver coins) and a cathode of carbon. Connect the anode (silver) to the positive terminal of a variable power supply and connect the cathode (carbon) to the negative terminal. Apply a current and raise it until the cathode just starts to bubble hydrogen and then lower it about 25%. Magnetic stirring and a stir bar should be applied to constantly shred the silver dendrites as they grow. Eventually the anode will be consumed and the solution is decanted to recover the silver powder. The silver powder is washed a few times with water and then dried by heating on the hot plate.

In this video we make luminol from domestically available chemicals. The process pretty complicated and dangerous at parts and so should only performed by, or under the direct supervision of, an experienced chemist. First we obtain diethylhexyl phthalate by refluxing 50g of finely cut vinyl gloves in enough isopropanol to completely cover them for at least one hour, preferably three to four. The alcohol solution of diethylhexyl phthalate is filtered and the supernatant is boiled until it reduces to half its volume. An equal amount of water along with 10g of sodium hydroxide is added and the mixture boiled for an hour. This causes the diethylhexyl phthalate to hydrolyze into phthalic acid and 2-ethylhexanol. After the solution cools it will phase separate into an aqueous layer containing disodium phthalate and an organic layer containing the alcohols. Retaining just the aqueous layer, 25mL of 12 molar hydrochloric acid is added to precipitate the phthalic acid. Chilling may be necessary. The supernatant is discarded and the residue of wet phthalic acid is purified and converted into phthalic anhydride by heating it to 300 Celsius. First the water boils off and then the phthalic anhydride evaporates and condenses on the sides of the beaker. At this point a flask of cold water is placed over the beaker to allow the phthalic anhydride to deposit on it. Periodically the phthalic anhydride deposits are harvested until no more can be obtained. ... https://www.youtube.com/watch?v=58Ve69s0qD0
