Curie point heat machine

When a magnet at the end of a wire is heated to a certain temperature (Curie point), its magnetic field is temporarily lost until it cools down.

This motor design utilizes a second magnet that pulls the swinging magnet back into the heat source, in this case a tea candle flame, once the magnetic field is restored. Repeating this process creates mechanical motion as long as the heat source is running.

Deionized water💧

If electrodes are placed in beakers and a high voltage is applied, deionized water forms a stable cylindrical bridge between the 2 beakers.

How to memorize the electrodes?

To memorize the processes at the anode and cathode, there are mnemonic rules.

Briggs-Rauscher reaction

Hydrogen peroxide in interaction with acid, as well as starch, gives out a reaction that is able to change the color of the liquid in the following stepwise transitions: colorless - golden - blue solution.

During the interaction of the ingredients, the solution will begin to change its color.

The ethyl alcohol trick

Alcohols, such as ethyl alcohol, are easily ignited. Ethanol burns to form carbon dioxide and water: C₂H₅OH + 3O₂ → 2CO₂ + 3H₂O

In this video, it is ethyl alcohol that is burning, not the bill. Sodium chloride gives the flame a yellow-orange color. The water with which the bill is moistened absorbs the heat generated.

But this heat isn't enough to completely vaporize the water. As a result, all the alcohol burns off, the flame goes out, and the slightly damp bill remains intact.

Sample gas emission spectra

Pure samples of hydrogen, nitrogen, and 5 noble gases are exposed to the high-frequency pulsed field of a miniature Tesla coil. Each gas has a characteristic breakdown voltage and emission spectrum.

Copper isn't magnetic, but it creates resistance in the presence of a strong magnetic field, causing the magnet to stop for a moment before it even touches the copper

A visualization of the working process of an electric light bulb

A light bulb, or incandescent bulb, is a simple device in which electrical energy is converted into light energy.

The light bulb shines due to the heating of a conductor (filament) by an electric current.
