Caustic soda

[Renato]

[Caustic soda] is the trade name of Sodium Hydroxide (NaOH), which is an agent used to clear drains of junk that has gotten there someway or other. It is allso a cheap source of [hydrogen] gas.
Put some in a bottle along with tin foil, add water and pull a balloon over the top. Watch as it inflates and there, you have a balloon o hydrogen.
It can manipulate your voice in a similar way to helium, but its cheaper, or when mixed with oxygen and lit it can manipulate other peoples voices into sounding as though theyre muted, along with sounds of any sort really.
Warning: Caustic soda is very [caustic], as one might understand. [Getting it in] your eyes is actually worse than getting a strong acid there.
Allso, a mixture of hydrogen and oxygen is quite volatile.
