Don't touch the glass wool with bare skin, it will be itching.

The glass grains are sharp crystals, like the regolith is, while the sand grains are smooth due to water and wind erosion.

In addition, due to the smooth surface and relatively low water absorption, glass sand can improve the fresh concrete properties [9].

Fun story, back then it was new some guy my father knew tried use it as an makeshift Santa Claus beard.  It was not conformable.

They show, what happens to the people, who did.

I have found an effective method to remedy this is to apply a layer of excessively adhesive tape (duct tape at the minimum) to the affected area and peel it off after a bit.    Usually pulls the glass fibers right out.    And all your hair.       But the itching has stopped.

This works.  Gorilla tape works very well.  Do not rub the skin as this will drive the fibers deeper

Yeah, don’t touch the thing that is driving you absolutely bonkers.     Good luck with that.

cold water always worked for me.

Cold water tends to work so long as the cold is being applied, but for longer lasting relief, take water just below the temp where it is painful on healthy skin, and apply it to the irritated skin.  

If it is not painful on healthy skin, it should not cause any damage, but on the irritated skin it will be painful, then after you remove the heat it will not itch for a while.

I suspect it is related to either desensitization or using up neurotransmitters for your pain receptors, so that it takes a while before the itch can return. (often long enough to fall asleep if you hold it under the hot water until it is no longer painful)

This is the most effective method I have found for dealing with the itch of poison ivy without damaging the skin by popping all of those fluid filled blisters with scratching.

Is there a nuclear reaction to convert Oxygen to Carbon and Hydrogen? Just like how rutherford's friends transmuted Nitrogen to oxygen?

Now it's a question, how to take the neutrons from O-16 to get O-11,12,13.

Nuclide [n 1]	Z	N	Isotopic mass (Da)[4] [n 2]	Half-life[5] [resonance width]	Decay mode[5] [n 3]	Daughter isotope [n 4]	Spin and parity[5] [n 5][n 6]	Natural abundance (mole fraction)
	Excitation energy							Normal proportion[5]	Range of variation
11 O [6]	8	3	11.05125(6)	198(12) ys [2.31(14) MeV]	2p	9 C	(3/2−)
12 O	8	4	12.034368(13)	8.9(3.3) zs	2p	10 C	0+
13 O	8	5	13.024815(10)	8.58(5) ms	β+ (89.1(2)%)	13 N	(3/2−)

P.S.

Or take an alpha-particle from O-16 to turn it into C directly.

Maybe intensive gamma may help, to make the O overexcited.
