It can conjure up many things I want.
Today is your birthday, and I want to give you something nice.
At the same time, I have to show that I have nothing in my hand but paper. But forget it, look, just paper! )
Then he reached out and took out his lighter, and at this time he took the necklace in his hand.
Thumb, forefinger with lighter, confession: I want to light it.
Then light it. At this time, get up quickly. Put the necklace in the hand that just took the fire paper.
It will work.
Try a few more You can try it first.
Remember, the process is indispensable. It is necessary to explain things.
Making method of fire paper:
We need concentrated sulfuric acid and nitric acid as raw materials, and rice paper.
The manufacturing method can refer to the manufacturing method of nitrocellulose (nitrocellulose).
(1) Prepare two cans of water. One glass tank is filled with half cold water and the other half with warm water at about 4 0℃, so as to adjust the temperature during the reaction.
(2) mixing the two acids. Firstly, 20 ml of concentrated nitric acid with a density of 1 .4g/cm3 was poured into a small beaker, then 4 ml of concentrated sulfuric acid with a density of 1 .84g/cm3 was slowly poured in, and gently stirred with a glass rod. Measure the temperature of mixed acid with thermometer. If it is higher than 30℃, soak the small beaker in a cold water tank; If it is below 30℃, put it in a cold water tank.
(3) Soak the rice paper evenly in the liquid15min. Carefully take out the rice paper. You can use tweezers with a glass rod, and be careful not to splash it on your hands. Soak rice paper in clear water and rinse it repeatedly, then remove the acid solution. Because paper is dry and flammable, don't do too much at a time. Usually it can be soaked in water or alcohol and dried before use.
note:
1)98% concentrated sulfuric acid is difficult to prove ~ (36% is ok)
2) Nitrification time should not be too long or too short, 15 minutes is enough.
3) Be sure to wash with water (pH=7) after nitrification.
4) produce toxic gas, pay attention to ventilation; Wear acid-proof gloves.
5) The container should be equipped with special glass instruments for chemistry, although stainless steel pots can be used!
6) Toilet paper is a flammable solid with unstable properties, and those whose nitrogen content exceeds 12.5% are explosives. In daily storage and use, water or ethanol is generally used as a stabilizer to wet the fire paper. If water and ethanol are evaporated, the dried nitrocellulose will easily cause spontaneous combustion after long-term storage and deterioration. Therefore, it is necessary to check the drying condition of stabilizer frequently at ordinary times to prevent spontaneous combustion fire accidents.
7) Note: Strong acid is dangerous, so don't spill it on your body.
