Sinks should fill containers with water

[enforcer9]

We need a new chemistry recipe where if you have a 2:1 ratio of hydrogen to oxygen in your container it becomes water. Why don't we have this already?

Oh no what ever will we do if you can't synthesise water when it can already be dispensed?

you should be able to mix water and hydrogen to make heavy water, although it's still called water just like holy water is. But if you end up with a certain amount of heavy water in your system (alot) you'll start taking toxic damage until you die (unless you somehow manage to flush it out of your body).

Of course, this is completely useless cause you'd need alot of D2O to die, but I'd definitely use it as my preferred method of slow painful suicides when i'm a scientist.
