"Shikigami whose curse is too powerful to burn" is reproduced in an experiment! The video that seems to transcend nature is fun (1/2 page)

The experiment "Shikigami that burns because the curse is too powerful" that spontaneously ignites humanoid paper using chemicals is shocking like the world of animation and horror movies.

Genki Ichioka (@genkiichioka), a science artist who conveys the charm of science, succeeded in an experiment to spontaneously ignite paper. I posted how a piece of paper like a shikigami (Katashiro) placed on a cardboard box spontaneously ignites and burns out in just a few seconds.

A small fire rises from the shikigami and black smoke erupts at the same time. The entire paper was quickly wrapped in fire, leaving only the charred shikigami on the box. If you just watch the video without knowing anything, it looks like an unusual event that transcends nature.

――I was worried that only Shikigami would burn and not move to the box below. What kind of material do you use for the experiment?

In the experiment, yellow phosphorus dissolved in carbon disulfide was used. Yellow phosphorus generates heat when it comes in contact with air and ignites at 60 ° C. Since carbon disulfide has a low ignition point of 90 ° C, the paper is burning, but the temperature is very low at 100 ° C or less, so there was not enough heat to burn the corrugated cardboard below. The ignition point of corrugated cardboard is said to be 200 ° C or higher.

--What are the precautions when handling yellow phosphorus?

Since it spontaneously ignites and is highly toxic, it can be stored underwater. If the bottle collapses and breaks due to an earthquake, or if you forget it and the water dries, it will ignite, so basically you shouldn't get it.

The minimum amount you can buy is 500 grams, which is about 60,000 yen. The amount used this time was less than 1 gram. It takes about 10 years to use up, and you need someone to manage it properly. Inhaling yellow phosphorus fume can cause death, so experiments like this one can only be done in a fume hood with a trap (* a device used in scientific experiments that generate harmful gas).

Yellow phosphorus is designated as a "Class 3 Dangerous Good" and requires qualifications for handling. Basically, it cannot be purchased by individuals, and it is difficult to manage because it spontaneously ignites unless it is soaked in water. For free study during summer vacation ... I don't think it can be said.

By the way, the reason why I came up with this experiment was that it was an experiment to reproduce the human soul that Genki-sensei released in the video in the past. Yellow phosphorus is also used in this experiment, and it is said that it is difficult to obtain and very dangerous. The appearance of the shikigami burning is cool like an anime or manga, but you can see again that it is a rare experiment that you can hardly see.
