Iron can burn❗️

Under normal conditions, the oxidation rate of iron depends strongly on its form: a simple piece of metal does not burn, but thin fibers of iron or fine powder can easily be ignited.

It all depends on the contact surface of the iron with the air: it should be enough so that the oxidation reaction can sustain itself.

Iron wool consists of fairly thin fibers of iron. Oxidation on such a surface produces enough heat to keep the reaction going, and it runs "on its own”.

In fact, the blood moves like this☝🏻

Kind of like the tremors that provide the contraction of the heart muscle. Precisely these jolts are the ones you can feel through the pulsation in certain points of our body.

Thus, the blood is not moving in a continuous flow, as it is shown in the movies.

Google showed an updated Google Maps at its presentation. Now, thanks to augmented reality, it will be possible to see in detail a 3D model of the world, which is more convenient to navigate and look for, for example, a parking lot or the right entrance.
It will also be possible to change the weather, look at traffic congestion and look inside any establishment.
