Devil's venom

Devil's venom was a nickname coined by Soviet rocket scientists for a liquid rocket fuel composed of a dangerous combination of nitric acid and hydrazine—specifically, hypergolic UDMH-nitric acid. It is extremely corrosive and toxic (it produces poisonous gas when burned), but is used in rocketry because this combination of fuel and the oxidizer hypergolic does not require an external ignition source, which makes rockets using these materials simpler. Further, both the fuel and oxidizer have high boiling points compared to other rocket fuels such as liquid hydrogen, and oxidizers such as liquid oxygen, allowing rockets to be stored ready for launch for long periods without the fuel or oxidizer boiling off and needing to be replenished.
