hahahahhahahahahhhahahaha.

I'm hilarious.

"Makes me want to give them heavy water." :P

Oh I see how it is! Hydrogen-peroxide gets to be funny but heavy water doesn't! Well ok, next time you come to one of my parties see if your ice floats or sinks! Besides, I think Dueterium and Tritium to be hilarious. So there. *sticks tongue out*

heavy water? does such a thing exist?

Yeah. Heavy water is water where at least one of the hydrogen atoms is an isotope other than regular old hydrogen. Usually Dueterium. The extra neutron or two obviously adds to the usual atomic weight of water, making it "heavy." It naturally occures in nature as like 1 of every 10,000 water molecules. Nuclear power plants like to use it as the water they use to make steam to spin the turbines. It's commercially available. Which is why I mention the party gag where you buy a bottle of heavy water, freeze it into ice cubes, and then watch people's amazement as the ice cubes sink like stones! Of course, consuming a whole lot will make you sick...so I hear anyway.

gotcha. that actually sounds really neat. but yeah. I just want to add an oxygen molecule.

Remember that Oxygen is an element, so it's in atoms. What exactly is the reaction that makes H2O2 fizz like it does? I never learned that one. Is it Oxygen gas bubbling out while the rest of the Hydrogen and Oxygen form water?

Yes. H2O2 isn't stable over long periods of time, it gradually turns into ordinary H2O and oxygen atoms (which combine into O2 oxygen gas bubbles).

You can speed up the fizzing by adding steel wool, which catalyzes the oxygen-release process, or by heating the H2O2 up.

You can slow the fizzing down by putting the H2O2 in very clean plastic bottles, or by adding small amounts of other chemicals that stabilize the solution.

Note that most H2O2 you can buy is pretty low concentration to begin with, and is mostly water. High concentration H2O2 can release lots of oxygen quickly, also releasing lots of heat, and is used in rocket fuel.

oh jeebus.

the point was that I wanted to poison someone.
