In this video we revisit making trimethyl orthoformate using sodium metal this time. The improvement is NOT worth it.

We show how to make glow sticks and go through all the chemicals needed as well as how to make different colors. We also talk about the chemistry and scientifically research a proposed mechanism.
To make the glow stick mix together the following:

We take cubes of regular ice and cool them with liquid nitrogen.
The ice made this way can be used to cool drinks and as long as you don't let the ice directly touch your mouth the drinks are safe. Once they warm back up to 0 degrees they can be treated exactly the same as regular ice.
Alternatively, just use a straw when using ice of this type.

I have a very exciting progress report: I've successfully made sodium by the alcohol catalyzed magnesium reduction approach!
After many failures i decided to go to other end of the spectrum and try an experiment constructed under ideal conditions that would have far greater chances of working. While it would be thousands of times more expensive to make sodium this way, it would nonetheless prove or disprove whether it was possible. If it failed, it would show it was impossible or just very hard and thus not worth pursuing with my limited time.
To do it, 10mL of 7-hexyl-7-tridecanol were placed in a flask with 0.5g sodium metal (to jump start the reaction). A reflux condenser was fitted over the flask and the contents heated until the sodium melted and dissolved. 3g of magnesium metal was added and heated for another 30 minutes. 4g of sodium hydroxide was added and heated for three hours. Tiny spheres of sodium formed as alcohol catalyzed the reaction of sodium hydroxide and magnesium metal.
This was a success. And thus proves that we can make sodium this way and thus it's worth to keep trying for cheaper conditions.

In this video we make ammonia gas and dissolve it water from various chemicals easily accessible to the amateur.
The first method is merely boiling household ammonia solution that's domestically available from the local supermarket. The ammonia boiled out is lead into cold water where it can be dissolved. While this did work the yield was quite low at around 2.5g per 100mL of household ammonia solution. From the 600mL of ammonia solution used only about 15g was obtained.
The second method was to revisit the classic method to produce sodium nitrate from ammonium nitrate and sodium hydroxide by dissolving them both separately in water and then mixing them together and trying to boil out the ammonia. This worked terribly and i got almost no yield at all.
The third method that seemed to work the best was to react urea and sodium hydroxide in water. This reaction was well-behaved, steady and easily performed with domestically available chemicals. Starting from 200mL water, 90g urea and 120g sodium hydroxide, about 38.6g of ammonia was obtained.
I intend to use the ammonia in a future project to make nitric acid.

Diamagnetism is the property of a substance to be repelled by a magnetic field. Interestingly enough, water shows this effect. We build a simple, but very sensitive detector to show this. We also show pyrolytic carbon that is so diamagnetic that it can float above magnets if they are arranged the right way.
Water is diamagnetic, meaning it's slightly repelled by a magnetic field. But in everyday life this is almost impossible to notice. We need to build a very sensitive detector to see it.
Just get a basin of water and float a styrofoam block in it. Styrofoam is very light and so even the small repulsive force of a test tube of water will have a noticeable push on it. Push the test tube of water into the center of the block and simply hold a strong neodymium magnet as close as possible to the tube without touching it. It's a very small force, but eventually the block will start moving away from the magnet.
Pyrolytic graphite, also called pyrolytic carbon, exhibits the same effect and can even be made to levitate on top of a magnet. A single magnet is unstable since the graphite will like to fall off the side. But having four magnets and arranging them like in the video will create a "void" in the center that the graphite "falls" into and remains stably levitated.

In this video we fail at making thermite from the gallium infused aluminum.
The objective was to see if the weak gallium infused aluminum could be used to make aluminum powder without going through the arduous filing step necessary for bulk aluminum. Turns out the gallium infused aluminum does crumble easily, especially with raised temperature, but doesn't become fine enough for thermite. Only filing bulk aluminum made it fine enough for thermite. Alternatively, just buying aluminum is usually the better option.
Another thing we tried was making gallium iron oxide thermite. Gallium has similar properties to aluminum so this wasn't a crazy idea. Turns out though gallium produces far too little energy to initiate a self-sustaining thermite reaction so that was a fail as well.

How to make Manganese Dioxide Electrodes that can be used for chlorate cells or HHO cells and a few other electrochemical processes requiring inert anodes in oxidizing solutions.
Make the electrode is fairly simple. First a titanium strip is sanded to give a clean surface and then etched with hydrochloric acid to activate it. Cobalt nitrate solution is applied in a thin layer and then heated to 300 Celsius to decompose (pyrolyze) the cobalt nitrate into cobalt oxide. the loosely adhering cobalt oxide is washed off and then new layers of cobalt oxide are applied. Usually between 3 to 10 layers.
Then manganese nitrate is applied and the process repeated to make manganese dioxide. Another 10 to 50 layers may be applied.
Optionally, a further layer of manganese nitrate by electrolysis may be applied by using the electrode as an anode in a solution of 90 grams manganese sulfate, 500mL water and 12mL concentrated sulfuric acid. Copper or titanium is used as the cathode and a current density of about 10ma per square centimeter is used. A short run time of a few minutes or so puts a thin layer of manganese dioxide on the surface that seems to reduce permanganate production, but does not eliminate it.
In the future i'll be working on a lead dioxide electrode.
