Clamping experiment with a powerful magnet and magnetic balls

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

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 .

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…

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.
