How To Galvanize Metal For Rust

How To Galvanize Metal (for Rust Protection)

We show you how to galvanize metal objects to protect them rust. First we get 30g of zinc sulfate and dissolve it into 100mL of water. Zinc sulfate was made back in our video on making a copper sulfate and zinc battery: www.youtube.com/watch?v=Id3tL2iI0Vw Then connect the item you want to galvanize to the negative terminal of a 5 volt power supply. Connect the positive terminal to a strip ...

Make A Solar Cell - Tio2/raspberry Based

In this video we show how to make a dye sensitized solar cell based on titanium dioxide and anthocyanin found in raspberries. First get some titanium dioxide (anatase structure), about 0.5g will do. Then mix it with drops of vinegar until it has the consistency of thin paint or liquid corrector fluid. Add a drop of dishwashing detergent. This is to make it stick to the glass. Now get a piece of indium tin oxide ...

Grow Silver Metal Crystals By Electrochemistry

In this video we grow crystals of pure silver metal by electochemistry. The procedure is fairly simple. Just apply an electric current between a silver anode and an aluminum or silver metal cathode while they are immersed in silver nitrate solution. The silver ions from the anode will deposit on the cathode. The crystals are microscopic so to see them the solution is placed under a microscope. A glass slide may be placed over the ...

Make An Aluminum Air Battery

We show how to make an Aluminum Air Battery Air batteries are batteries that use oxygen from the air as an oxidant for their chemistry. Most batteries on the other hand carry another chemical as their oxidant. Air batteries are currently being researched by scientists as a means of energy storage for everything from cars to laptops. The aluminum air battery is one of the simplest to make. To do just mix 60 grams of salt ...

Make A Zinc Air Battery

In this video we show how to make a Zinc Air Battery. First you'll need to make a solution of 50g of sodium hydroxide in 150mL of water. Stir it until it completely dissolves. Be careful as it will heat up a lot. Set it aside to cool. Now get a zinc sheet (we cut one out of a carbon zinc battery in a previous video: www.youtube.com/watch?v=knc1lSupAwQ) and attach ...

Make A Gallium Beating Heart

In this video we make a blob of gallium beat like some weird alien heart attack. To do it, add 2g of gallium to a 10mL solution of 6M sulfuric acid and warm it up on a hot plate to 50 Celsius. It'll pull together to form a sphere of gallium. Now carefully touch the gallium with an Iron nail or iron wire. What's happening is first the gallium is reacting the sulfuric to form gallium ...

Make An Aa Battery

In this video we’ll show how to make an AA battery. Warning: Potassium hydroxide is corrosive, zinc is a heavy metal, and manganese dioxide is an irritant. Wear gloves when handling them. Get a 5 mL plastic syringe (the one i got was from a company called “BD” and the catalogue number was 309603). Discard the plunger and cut off the tip. Also cut the back up to the 5 mL mark. Get a 5 by 3 cm sheet ...
