THIS PART OF THE PRESENTATION IS ABOUT SWIMMING POOLS*

the part below me forces capital letters

*instead of poisonous gas

here comes a lot of textThe swimming pool exterior/container for the water is

usually made out of plastics and cements. The pool water itself has a small level of chlorine, with cyanuric acid as a stabilizer.

Calcium hypochlorite is also used to “shock” bacteria that chlorine doesn’t catch. Sometimes, Bromine is used instead of Chlorine. It works better, but costs more. Obviously, one of the

main ingredients in pool water is water (or H20). Without chlorine in pools, pools would constantly be bacteria-ridden.

Chlorine is usually found buried under the surface of the Earth in rock salt or halite, where water is found all over the world. Bromine is found in the earth’s crust (and in seawater). Not

much Chlorine is used in swimming pools, at least not enough for it to be deadly. Water is usually not deadly by itself, except in

cases of suffocation.
