I think a lot of the above is difficult to do at home. And it should be copied online.
I'm going to give you an interesting experiment. Believe you did absolutely love to die chemistry.
Spontaneous combustion: you put a little bit of potassium permanganate powder on a piece of paper at home, the paper is better placed on glass, because it will burn up, it will burn the table, then add a little glycerin to potassium permanganate, and it will burn after a while. (Glycerin should be thick, dilute and not burn, only a lot of white smoke can be seen) This is the "truth" that I have discovered at home, and if no one knew about it before, I would be the one who discovered a new phenomenon.
It's a pity that after I checked the information, I found that this reaction has long been known. At that time, I was only in my third year of junior high school, and I had just studied chemistry, and since I discovered this reaction, I have formed a deep relationship with chemistry...
This reaction is a redox reaction that produces potassium carbonate and manganese dioxide.

When I was in middle school, I was a girl, but I was good at chemistry, but physics was very different, which made me and my teacher feel strange.
I don't know if I can learn chemistry well because I really like it and am interested? Or is it because of my chemistry teacher's preference for me? Anyway, the chemical trim that made many girls feel a headache at that time, I did it "with relish".
I just got the book "Chemistry is Super Interesting" by Mr. Chen Weijun, and I feel very kind, maybe I think of the wonderful middle school days.
Chemistry is super interesting, this book takes common phenomena or events in life as examples, with humorous illustrations, to explain the chemical principles behind phenomena or events that we have never thought deeply about, such as atomic structure, nuclear reactions, concentration, pH, redox and so on.
Chemistry is life", in this book, the author turns his imagination of the world of chemistry into a light-hearted and interesting text, showing us the charm of chemistry in another way, and this process does not require you to take out a pen and paper to calculate. At the moment of traditional education, when popular science knowledge has become a tool for college entrance examinations, such an interesting popular science book is indeed very suitable for young people to read.
When explaining that gas is insoluble in water, he mentioned that if the fart can't be dissolved in water, why is there sparkling water, and the carbon dioxide of those carbonated drinks is fused into it, as long as it sways, it will overflow with a piece of the drink, and people will involuntarily burp and run out by themselves after drinking?
When it comes to real gold, it is not suitable to be afraid of fire refining, because the melting point of gold is only 1000 degrees Celsius, but compared with some other metals, this is also the level of the younger brother, for example, the melting point of tungsten wire can reach 3400 degrees Celsius, otherwise the bulb will not be afraid to use this metal as a wick.
The so-called real gold is not afraid of fire, and it should be understood that no matter how the gold is heated, it will not rust or deteriorate, and it will always maintain its golden appearance, so that it is appropriate.
In this way, chemistry is not boring, and it is indeed closely related to our lives. "Chemistry is Super Interesting", extracts the chemical knowledge in life, and explains these chemical knowledge very humorously, so that I will no longer be afraid of chemistry, and even fall in love with chemistry.
Chemistry is not only fun, but also very practical, and using it well will enrich everyone's life!

Dripping water to make a fire experiment.
Place a small piece of sodium metal in the middle of the wick of an alcohol lamp and drip it over with a dropper to start a fire.
Principle: Sodium metal can react with water, and release a large amount of heat, igniting the wick, and at the same time, the reaction also generates hydrogen, which can quickly make a fire.
